Privacy Policy
Last updated: July 2, 2026
Burnoff.fyi (“Burnoff,” “we,” “us”) helps people in the San Francisco Bay Area discover lectures, talks, salons, and similar events. This policy explains what information the Burnoff mobile app and website handle, and how.
We’ve tried to keep this short and plain, because the honest answer is: we collect very little.
The short version
- You can browse all events without an account and without giving us any personal information.
- Events you save are stored only on your device — we never receive them.
- If you use Ask AI, the text of your question is sent to Google’s Gemini service to generate the answer. We don’t store your questions or the answers — not even in logs — and nothing you ask is tied to your identity.
- The only time we collect personal information is if you choose to use the “Submit an event” / “Missing an event? Let us know” form, which asks for your email so we can follow up.
- We do not sell your data, show ads, or track you across other apps or websites.
What we collect, and when
Browsing (no personal data)
When you open the app or website and browse events, we serve the public event listings from our database over an encrypted (HTTPS) connection. We do not require a login, and we do not attach your identity to this activity.
Events you save (stored on your device only)
When you bookmark/save an event, that preference is stored locally on your device. It is not sent to us or to any server. If you delete the app, your saved events are removed with it.
App preferences (stored on your device only)
Settings such as your light/dark theme choice are stored locally on your device and are not sent to us.
Adding an event to your calendar (stored on your device only)
When you use “Add” to put an event on your calendar, the event is created by your device’s own calendar system (or by opening your calendar provider’s website). We receive nothing when you do this.
Asking the AI (not stored, not tied to you)
The optional Ask AI feature lets you describe what you’re in the mood for and get event suggestions. When you use it:
- The text of your conversation (your questions and the AI’s replies so far) is sent to our server, which forwards it to Google’s Gemini API to generate the response. To answer, the AI may also run Google web searches.
- Your questions are not tied to your identity — the feature works without an account, and we don’t attach any user or device identifier to requests.
- We do not store your questions or the AI’s answers. Each conversation lives only on your device while you use it; our server keeps no copy and no session. Our internal usage log records anonymous technical metrics only (model name, token counts, response time, estimated cost) — never the question, the answer, the search queries, your IP address, or anything identifying.
- Your IP address is briefly processed in memory to prevent abuse (rate limiting) and is not stored.
- Google processes the conversation text as a service provider under its own terms. Don’t include personal or sensitive information in AI questions — the feature only needs to know what kind of events you’re looking for.
Submitting an event (the one time we collect personal data)
If you use the form to suggest an event, we collect:
- Your email address (required) — so we can contact you about the suggestion if needed;
- Your name (optional);
- A comment (optional); and
- The event link you provide.
We use this information solely to review and, where appropriate, add the suggested event, and to follow up with you about your submission. We do not use it for marketing.
How information is stored and processed
The event database and the event-submission form are hosted on Supabase, a third-party cloud database provider, which stores this information on our behalf. Data is transmitted over encrypted connections.
The Ask AI feature runs through our server (hosted on Vercel) and is powered by Google’s Gemini API, which processes conversation text to generate responses (see “Asking the AI” above). We do not store that text on either.
The app delivers updates through Expo Application Services (EAS). When the app checks for or downloads an update, standard technical request information (such as device/OS type and app version) may be processed by Expo to deliver the correct update. See Expo’s privacy policy at expo.dev/privacy ↗.
The app is distributed through the Apple App Store. Apple may collect information related to downloads and usage as described in Apple’s privacy policy.
We do not currently use third-party advertising or analytics SDKs in the app.
The website (not the app) uses Cloudflare Web Analytics to count page views. It is a privacy-focused tool that sets no cookies, does not fingerprint devices, and does not track you across sites — it tells us how many people visited, not who they are.
Data retention
- On-device data (saved events, preferences) remains until you delete the app or clear it yourself.
- Event submissions are retained for as long as needed to review them and maintain the event listing. You may ask us to delete your submission and associated contact details at any time (see “Contact”).
Children’s privacy
Burnoff is intended for a general adult audience and is not directed at children under 13. We do not knowingly collect personal information from children.
Your choices and rights
- You can browse everything without providing any personal information — the submission form and Ask AI are both optional, and you control what you type into them.
- You can request access to, or deletion of, any personal information you’ve submitted by emailing us (see below).
- You can remove all on-device data (saved events, preferences) by deleting the app.
Changes to this policy
If we change how we handle information — for example, if we add user accounts, analytics, or crash reporting in a future version — we will update this policy and revise the “Last updated” date above.
