Terms of Service

Last updated: August 7, 2026

These Terms of Service (“Terms”) govern your use of stumblapp.com (the “Site”) and the Stumbl iOS app (the “App”), both operated by Spaghetti Labs, LLC, a California limited liability company (“we,” “our,” or “us”). By using either one, you agree to these Terms. If you do not agree, please do not use them.

1. Agreement to these Terms

These Terms are a binding agreement between you and Spaghetti Labs, LLC. They apply the moment you use the Site — browsing counts — and when you download, install or use the App.

The Site is free and requires no account, so there is nothing to sign. If you do not accept these Terms, your remedy is to stop using the Site and the App.

Sections 1 through 14 and 16 through 25 apply to everyone. Section 15 applies only if you use the iOS app.

2. Event information is not a guarantee

This is the most important thing on this page, so it is near the top rather than buried at the bottom.

Stumbl aggregates event information from calendars other organizations publish. We do not run the events, staff them, fund them, inspect them or control them. We have no advance notice when one changes.

We make no representation or warranty that any listing is accurate, complete, current, or that the event will take place at all. In particular, we do not warrant that:

• the event will happen, or happen at the date, time or place shown;
• the event is free, or costs what the listing says;
• registration is still open, or that space will be available when you arrive;
• the event is suitable, safe or age-appropriate for your child;
• the venue is accessible, has parking, or has facilities of any kind;
• the event has not been cancelled, moved, rescheduled or already filled.

Before attending anything you found here, confirm the details directly with the organizer through the source link on the event page. Every listing on Stumbl carries one. You attend events at your own risk and are responsible for your own and your children’s safety, supervision and wellbeing.

3. Using the Site

• The Site is free. There is no paywall, no subscription and no metered access.
• There is an optional tip jar (Section 11). Contributing is voluntary, it buys nothing, and the Site is identical either way.
• No account is required and none is offered. We do not ask who you are.
• You may use the Site for your own personal, non-commercial purposes: finding things to do, planning outings, and sharing individual event links with friends.
• You are welcome to link to any page on the Site. You do not need permission, and we will not ask you to take a link down.
• The Site is intended for adults planning activities. Nothing on it is directed at children under 13.

4. Where event information comes from

Listings are compiled from publicly published calendars and program pages belonging to libraries, parks and recreation departments, regional park districts, museums, city governments, farmers’ market operators and comparable community organizations across the Bay Area. Our sources are named on the Sources page.

What we publish about an event is descriptive factual data: title, a short description drawn from the organizer’s own listing, date and time, venue and address, age guidance, cost, and a link back to the original page. We summarise and truncate rather than republish source pages in full.

Attribution is not optional for us. Every event page names its source and links to the organizer’s own listing. Facts about public events — that a storytime happens at 10:30 on Tuesday — are not owned by anyone, but the expression of a description, and any photograph, belongs to whoever wrote or took it. We treat those accordingly, and Sections 5 and 6 explain how to reach us if we have got something wrong.

Nothing on the Site implies that an organization endorses, sponsors or is affiliated with Stumbl. We list events; we do not partner with the venues unless we say so explicitly.

5. Corrections and removal requests

If you organize an event, run a venue, or hold rights in material that appears on the Site and something is wrong — or you simply do not want to be listed — email contactstumblapp@gmail.com with the subject line “Listing correction” or “Listing removal.”

Please include:

• The URL of the Stumbl page in question, and the event title as it appears there.
• The URL of your original listing, if there is one.
• What is wrong, or what you want removed — a single listing, a recurring series, or everything from your organization.
• Your name, role and organization, and a contact address we can reply to.

What we will do. We acknowledge requests within 5 business days and act on them within 10 business days. Straightforward removals are usually done the same day. If you want your organization excluded going forward, we will add you to a do-not-ingest list so your events do not reappear at the next refresh — that part is permanent until you ask us to reverse it.

We honour robots.txt directives on the sites we read, and we will stop reading any source that asks us to, for any reason or none. You do not have to justify the request.

Corrections we cannot make: we cannot change what appears on your own website, and we cannot guarantee that a search engine or AI assistant which previously indexed a Stumbl page will refresh its copy on any particular schedule.

6. Copyright and DMCA notices

We respect copyright and expect the same in return. If you believe material on the Site infringes a copyright you own or control, send a written notice to our designated agent:

Under 17 U.S.C. § 512(c)(3), your notice must include:

1. A physical or electronic signature of the copyright owner or a person authorised to act on their behalf.
2. Identification of the copyrighted work claimed to have been infringed.
3. Identification of the material that is claimed to be infringing, with enough detail for us to locate it — the Stumbl URL is ideal.
4. Your contact information: address, telephone number, and email address.
5. A statement that you have a good-faith belief that the disputed use is not authorised by the copyright owner, its agent, or the law.
6. A statement, made under penalty of perjury, that the information in the notice is accurate and that you are the copyright owner or authorised to act on their behalf.

Counter-notification. If material of yours was removed and you believe that was a mistake or a misidentification, you may send a counter-notice to the same address containing your signature, identification of the removed material and where it appeared, a statement under penalty of perjury that you have a good-faith belief the removal resulted from mistake or misidentification, and your name, address and telephone number together with consent to the jurisdiction of the federal court for your district (or the Northern District of California if you are outside the United States).

Repeat infringers. We will exclude sources that repeatedly generate valid infringement claims, and we will terminate the accounts of App users who repeatedly infringe.

Please note that under 17 U.S.C. § 512(f) you may be liable for damages if you knowingly misrepresent that material is infringing.

7. Acceptable use

Use the Site the way a parent looking for a Saturday morning would. Specifically, you agree not to:

• Systematically download, copy, mirror or extract listings in bulk (see Section 8).
• Republish the aggregated feed wholesale — whether as a competing calendar, a dataset, an app, a newsletter or a model training corpus — or otherwise reproduce a substantial portion of the Site.
• Strip, obscure or falsify source attribution or links back to the original organizer.
• Attempt to overload, degrade, probe, or disrupt the Site, its servers, or its network; or circumvent rate limits, caching, or any access or security control.
• Use the Site to break the law, infringe anyone’s rights, or harass, endanger or defraud anyone.
• Misrepresent an affiliation with, or endorsement by, Stumbl, Spaghetti Labs, LLC, or any listed organization.
• Introduce malware or attempt to gain unauthorised access to any part of our systems.

What is welcome: linking to us, quoting a listing or two with attribution and a link, screenshotting a page for your parents’ group chat, and telling other people about the Site. None of that needs our permission.

We may restrict or block access — by IP address, network, or user agent — where we reasonably believe this section is being violated. Given that the Site has no accounts, blocking is the only enforcement mechanism available to us, and we will use it sparingly.

8. Crawling, scraping and APIs

We want search engines and AI answer engines to read this site. Our robots.txt welcomes them explicitly.

• Reasonable crawling is permitted if it honours robots.txt, identifies itself with an honest user agent, and requests pages at a rate that does not degrade the service for anyone else.
• Bulk extraction is not permitted. That includes headless-browser harvesting, distributed or rotating-proxy crawling designed to evade rate limits, and any automated collection whose purpose is to reconstitute our event dataset elsewhere.
• The internal JSON endpoint that powers on-page filtering is not a public API. It exists to serve this website. It is undocumented, unversioned, and may change or disappear at any time without notice. Do not build anything on it.
• A public API may be offered in future under separate terms, and we would rather people used that than scraped the HTML. If you want structured access to Bay Area family event data, email contactstumblapp@gmail.com and tell us what you are building.

If you are an organizer whose own events are being listed, you never need permission to use your own data.

9. Saved events

The Site lets you save events for later. Saved events live in your own browser’s local storage. They are not an account, they are not stored on our servers, they are not backed up, and they do not sync between devices.

If you clear your browser data, browse privately, or switch device or browser, your saved events are gone and we cannot restore them, because we never had them. See the Privacy Policy for the detail.

10. The newsletter

• The newsletter is free and entirely optional. Signing up requires only an email address.
• Only subscribe an address you control. Do not sign anyone else up.
• We send a weekly digest of Bay Area family events and occasional short notes about the Site. We may change the frequency, format, or stop sending it entirely.
• Every email carries a one-click unsubscribe link. You can also email contactstumblapp@gmail.com.
• Everything in Section 2 applies to events described in the newsletter just as it does on the Site: confirm with the organizer before you go.

11. Voluntary contributions

The Site is free and stays free. It isn’t free to run, so there is an optional tip jar: if you find the calendar useful and want to chip in toward what it costs, you can. Nobody has to, nothing on the Site is withheld from people who don’t, and we are not going to nag you about it.

• A contribution buys you nothing. There is no ad-free tier, no early access, no extra features, no members’ area, no badge and no perks of any kind. The Site, its listings and every one of its features are identical for someone who contributes and someone who never does. That is deliberate: it is what keeps “free, no paywall” true.
• We are a business, not a charity. Spaghetti Labs, LLC is a for-profit California limited liability company. It is not a registered charity and not a 501(c)(3) organization. Contributions are not tax-deductible charitable donations, we do not issue tax receipts, and nothing we publish should be read as claiming otherwise.
• It is not a purchase and not a subscription. You are not buying goods or services, you are not signing up for anything recurring, and no ongoing obligation is created on either side. We owe you no deliverable, and you owe us nothing afterward.
• Contributions buy no influence. They do not buy a listing, placement, listing priority, a better position in search or category pages, inclusion of a source, or any say over editorial decisions or which calendars we aggregate. If you organize events, contributing does nothing for your listings, and not contributing costs them nothing. We will not take money in exchange for coverage.
• Stripe handles the payment. The link takes you to a payment page hosted by Stripe, Inc., and everything about the payment happens there under Stripe’s own terms and privacy policy. We are not a party to that payment relationship beyond receiving the funds, and we never see or store your card details. The Privacy Policy sets out exactly what we can and cannot see.
• Refunds. Changed your mind, mistyped the amount, or someone used your card without asking? Email contactstumblapp@gmail.com and we will refund it. No form, no deadline, no argument, and no reason required.
• Disputes and chargebacks go through Stripe’s process, and we will cooperate with it. If you would rather just ask us, the line above is faster and gets you the same money back.
• We do not promise where the money goes. It offsets what the Site costs to run: hosting, the domain, and the time spent maintaining the connectors that keep listings current. It is not held in a separate fund, and we make no commitment about how any particular dollar is spent.
• Only contribute using a payment method you are entitled to use, and only if you are old enough to enter into these Terms.

The tip jar is a feature like any other, and Section 13 applies to it: we may change it or remove it at any time.

12. Links to other sites

The Site links out constantly — to every source listing, and to venues, organizers and maps. We do not control those sites, we do not endorse them, and we are not responsible for their content, accuracy, availability, security, or privacy practices. Once you click through, that organization’s terms and privacy policy govern, not ours.

13. Changes to the service

Stumbl is an evolving, independently run project. We may add, change, restrict or remove features, pages, cities, categories or sources at any time; we may change how listings are organized or presented; and we may suspend or discontinue the Site in whole or in part. Because the Site is free and requires no account, we do not owe you notice, a refund, or continuity of any particular feature — though for anything significant we will try to say so in the newsletter.

14. Our intellectual property

The Stumbl name and logo, the design and layout of the Site and App, our written copy, our guides, our editorial categorisation and the software behind all of it are the property of Spaghetti Labs, LLC and are protected by copyright, trademark and other laws.

Underlying facts about public events are not owned by us and we make no claim to them. Descriptions and photographs originating with a source organization remain that organization’s property; we display them under Section 4 and remove them on request under Sections 5 and 6.

You are granted a limited, non-exclusive, non-transferable, revocable licence to use the Site and App for personal, non-commercial purposes in accordance with these Terms. You may not copy, modify, distribute, sell, lease or create derivative works from them except as these Terms allow.

15. If you use the Stumbl iOS app

This section applies only to the iOS app, which is a separate product with accounts, friends, check-ins and an optional subscription. Website visitors can skip it.

15.1 Eligibility and accounts

• You must be at least 18 years old to create an account. By using the App you represent that you are, and that you have capacity to enter into these Terms.
• You must provide a valid phone number, verified by SMS. One account per phone number.
• You are responsible for the security of your account and device, and for all activity under your account.
• You agree to keep your profile information accurate. You may not create accounts for others or transfer your account.
• Children may not create accounts or use the App independently.

15.2 Acceptable use in the App

In addition to Section 7, you agree not to:

• Use the App to stalk, harass, threaten or intimidate anyone.
• Share another person’s location without their consent.
• Create fake profiles or impersonate any person or entity.
• Use the App for any unlawful purpose, including anything that endangers children.
• Use the App for commercial solicitation, advertising or spam.
• Attempt to access other users’ data or accounts without authorisation.
• Reverse-engineer, decompile, disassemble or tamper with the App or its backend services.
• Post offensive, abusive, defamatory or inappropriate content in profile photos, activity notes or feedback, including nudity, violence or hate symbols, or a profile photo that is not a reasonable depiction of you.
• Share group invite links publicly without the group creator’s consent, or generate, distribute or consume invite links by automated means.
• Create groups for spam, harassment, solicitation or illegal activity.

Group creators and admins are expected to make reasonable efforts to moderate their groups and address violations by members. We may remove groups or restrict group features that violate these Terms.

15.3 Friends, groups and in-person meetups

• Friend connections are mutual — both people must add each other. You can remove friends or mute them at any time.
• When you check in, your location and activity are shared with your confirmed friends, or with the friend groups you select.
• Joining a shared group makes you mutual friends with the other members and shares your display name, profile photo and phone number with them, and theirs with you. Group admins may remove members and revoke invite links.
• Only add people you know and trust.

Assumption of risk. The App is a coordination tool. We are not responsible for the conduct of any user or for the safety of any in-person meetup arranged through it. You assume all risk of meeting other people in person. Use your judgment, meet in public places, and take sensible precautions.

15.4 Your content and family information

You retain ownership of what you create in the App (display name, profile photo, activity notes, feedback). You grant us a limited, non-exclusive, royalty-free, worldwide licence to use, display, reproduce and transmit it solely as needed to provide the App’s features to you and your friends. We may remove content that violates these Terms without prior notice.

You represent that you have the authority to share information about the family members you add to your profile, that you are responsible for its accuracy, and that you have obtained any consent required.

15.5 Push notifications

The App sends notifications about friend activity, meetup responses, friend requests, group events and event reminders. You control them through your device’s system settings, per-friend muting, the notification radius setting (2, 5 or 10 miles), Do Not Disturb mode, and per-group preferences.

15.6 Stumbl+ subscription

Stumbl+ is an optional paid subscription inside the App. The events calendar on this website is free for everyone and is not part of any subscription.

• Plans: $2.99 per month, or $24.99 per year. Prices may change; we will tell you in advance of your next billing cycle, and continuing after the change takes effect means you accept it.
• Free trial: new users receive a 28-day free trial, once per account. No payment information is required to start it.
• Payment: all payments are processed by Apple through the App Store and are subject to Apple’s terms. Charges are made to your Apple ID at purchase, or at the end of a free trial. Spaghetti Labs, LLC does not collect, store or process payment information.
• Auto-renewal: your subscription renews automatically at the end of each period unless you cancel at least 24 hours before it ends. By subscribing you consent to automatic renewal billing. Apple emails you a confirmation at purchase and before each renewal.
• Cancelling: open Settings on your device → tap your name (Apple ID) → Subscriptions → Stumbl+ → Cancel Subscription. Cancellation takes effect at the end of the current period; you keep access until then.
• Refunds: no partial refunds for unused portions of a billing period. Because Apple processes all payments, refund requests must go to Apple through its standard refund process. We cannot issue refunds directly.

15.7 Apple Licensed Application End User Licence Agreement

You acknowledge that these Terms are between you and Spaghetti Labs, LLC only, and not with Apple Inc. (“Apple”). Your use of the App is also subject to Apple’s Licensed Application End User Licence Agreement (“Apple EULA”), incorporated here by reference; where the two conflict, the Apple EULA governs to the extent of the conflict. Apple has no obligation to furnish maintenance or support for the App, is not responsible for any product warranties whether express or implied, and is not responsible for addressing any claims relating to the App. Apple is a third-party beneficiary of these Terms and may enforce them against you.

15.8 Termination of App accounts

• By you: delete your account at any time from the Profile tab. This permanently removes your profile, profile photo, friends, check-ins, favorite locations, feedback and friend requests from our servers.
• By us: we may suspend or terminate your account, with or without notice, if you violate these Terms or if we reasonably believe your conduct poses a risk to other users, to us, or to third parties. We may also terminate accounts inactive for an extended period.
• On termination your licence to use the App is revoked immediately. Sections that by their nature should survive — Disclaimers, Limitation of Liability, Indemnification and Dispute Resolution — continue to apply.

16. Disclaimers

THE SITE, THE APP, AND ALL EVENT INFORMATION ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY OR OTHERWISE. To the fullest extent permitted by applicable law, we disclaim all warranties, including implied warranties of merchantability, fitness for a particular purpose, title, accuracy, and non-infringement.

Without limiting the foregoing, and in addition to Section 2, we do not warrant that:

• Any event listing is accurate, complete or current, or that the event will occur.
• The Site or App will be uninterrupted, timely, secure or error-free.
• Location, mapping or distance data will be accurate or reliable at all times.
• Notifications or newsletter emails will be delivered promptly, or at all.
• Defects or errors will be corrected.
• The Site or App is free of viruses or other harmful components.

Stumbl is an index of other people’s events and a coordination tool. We are not the organizer of any event listed, and we are not responsible for the safety, conduct, quality or outcome of any event you attend or any meetup you arrange. You are responsible for supervising your own children and for your family’s safety.

17. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL SPAGHETTI LABS, LLC, ITS OFFICERS, MEMBERS, EMPLOYEES, AGENTS OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, INCLUDING DAMAGES FOR LOSS OF PROFITS, GOODWILL, DATA, USE, WASTED TIME OR TRAVEL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH:

• Your use of, or inability to use, the Site or the App;
• Any inaccuracy, omission, cancellation or change in any event listing;
• Any event you attend, fail to attend, or travel to after finding it here;
• The conduct, content, acts or omissions of any organizer, venue, user or third party;
• Any in-person meetup arranged, suggested or facilitated through the App;
• Content shared within shared groups, or invite links used outside the App;
• Unauthorised access to, alteration of, or loss of your data;
• Loss of saved events stored in your browser;
• Any other matter relating to the Site or the App.

IN NO EVENT SHALL OUR TOTAL AGGREGATE LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SITE, THE APP OR THESE TERMS EXCEED THE GREATER OF (A) THE AMOUNT YOU HAVE PAID US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100). For visitors who use only the free website and have never contributed, that amount is one hundred U.S. dollars.

Some jurisdictions do not allow the exclusion or limitation of certain damages, so parts of the above may not apply to you. In those jurisdictions our liability is limited to the fullest extent the law permits.

18. Indemnification

You agree to indemnify, defend and hold harmless Spaghetti Labs, LLC, its members, officers, agents, affiliates and licensors from and against any claims, damages, obligations, losses, liabilities, costs and expenses (including reasonable attorneys’ fees) arising from or related to: (a) your use of the Site or App; (b) your violation of these Terms, including Sections 7 and 8; (c) your violation of the rights of any third party; (d) content or information you submit; or (e) any event or in-person meetup you attend or arrange.

19. Dispute resolution

19.1 Binding arbitration

You and Spaghetti Labs, LLC agree that any dispute, claim or controversy arising out of or relating to these Terms, the Site or the App (“Disputes”) shall be resolved through binding individual arbitration rather than in court, except as set out below. Arbitration shall be administered by JAMS under its Streamlined Arbitration Rules and Procedures, or by another mutually agreed provider. It shall take place in the State of California, at another mutually agreed location, or remotely by videoconference if both parties agree. The arbitrator’s decision is final and binding and may be entered as a judgment in any court of competent jurisdiction.

19.2 Small claims exception

Either party may instead bring an individual action in small claims court for Disputes that qualify, so long as it remains in that court and is not removed or appealed to a court of general jurisdiction.

19.3 No class actions

You and Spaghetti Labs, LLC agree that Disputes shall be resolved on an individual basis only. Neither party may bring a claim as a plaintiff or class member in any class, consolidated or representative action. The arbitrator may not consolidate more than one person’s claims or preside over any form of class or representative proceeding.

19.4 Opt-out

You may opt out of this arbitration agreement by sending written notice to contactstumblapp@gmail.com within 30 days of first accepting these Terms. Your notice must include your name, an email address or phone number we can use to identify you (for App users, the phone number on your account), and a clear statement that you wish to opt out of binding arbitration. If you opt out, Disputes are resolved in the courts described in Section 20.

20. Governing law and venue

These Terms are governed by and construed in accordance with the laws of the State of California, United States, without regard to its conflict of law provisions. If arbitration does not apply — including if you have opted out under Section 19.4 — you agree to submit to the exclusive personal jurisdiction of the state and federal courts located in Alameda County, California, for any Disputes not subject to arbitration.

21. Availability and force majeure

We do not guarantee that the Site or App will be available at all times. Both may be interrupted for maintenance, upgrades, or network or equipment failures. We are not liable for any delay or failure to perform resulting from causes beyond our reasonable control, including acts of God, natural disasters, pandemic, war, terrorism, labour disputes, government action, power outages, internet or telecommunications failures, upstream provider outages, or cyberattacks. The same applies when a source organization changes or takes down the calendar we read.

22. Changes to these Terms

We may modify these Terms at any time. When we make material changes we will update the “Last updated” date at the top of this page, and for changes that affect App users we will also notify you in the App. Continued use after changes are posted constitutes acceptance. If you disagree, stop using the Site, and delete your App account if you have one.

23. Privacy

Your use of the Site and App is also governed by our Privacy Policy, which explains what we collect and why — including the fact that browsing the Site requires no account, sets no cookies, and involves no advertising or cross-site tracking. Please read it.

24. General provisions

• Entire agreement: these Terms and the Privacy Policy are the entire agreement between you and Spaghetti Labs, LLC regarding the Site and App.
• Severability: if any provision is found unenforceable or invalid, it will be limited or removed to the minimum extent necessary and the rest remains in full force.
• Waiver: our failure to enforce any right or provision is not a waiver of it.
• Assignment: you may not assign these Terms without our prior written consent. We may assign them without restriction.
• No third-party beneficiaries: except for Apple as stated in Section 15.7, these Terms create no third-party beneficiary rights.
• Headings: section headings are for convenience and do not affect interpretation.
