Privacy Policy
Effective date: 29 September 2026
Who we are
Oxformals helps Oxford students find, list and swap seats at college formals. The controller of your personal data is Nobel Suhendra, 140 Kingston Road, Oxford OX2 6RP. Contact us about anything in this policy at team@oxformals.com.
What we collect and who sees it
We collect what you give us and what you do on Oxformals. Nothing is bought from third parties.
Share images (for Instagram stories) show only a first name, or no name for anonymous reviews and private accounts.
Why we use it
We don't sell your data, show ads or make decisions about you by automated means alone.
Service providers and transfers
These companies process data for us, under contract and only on our instructions:
- Convex — Database, file storage and backend.
- Vercel — Hosts the website.
- Resend — Sends our emails.
- Expo — Delivers push notifications to the mobile app.
- OpenAI — Automatically checks bios and college tips for abusive content before they're published, and reads University Card photos. Reports from members, and cards it can't confirm, are reviewed by a person.
All of them are based in, or store data in, the United States. We rely on the UK Extension to the EU–US Data Privacy Framework (the “UK–US data bridge”) where the provider is certified, and otherwise on the UK International Data Transfer Addendum to the EU Standard Contractual Clauses.
How long we keep it
- Sign-in codes: 10 minutes, single use.
- Sign-in cookie: 7 days. Server sessions end after 30 days, or when you sign out.
- Your account: until you delete it. Past listings and requests stay with your account until then.
- Server logs: as long as our hosting providers keep them, typically days to weeks.
When you delete your account we remove your profile, email, sign-in records, follows, likes, bookmarks, comments, tips, votes, reports, badges, wishlist, push tokens, spoon balance and every photo or file you uploaded, and blank the free text on your requests. Some records are kept, without your name, because other people rely on them:
- Messages you sent stay in the other person's chat, shown as from “Deleted user”, for 12 months.
- Your college reviews (text and ratings, not photos) stay, shown as by “Deleted user”, for 24 months.
- Seat-credit records stay so other members' balances add up, for 2 years after the formal (or after a dispute about it is settled, if later).
- Records of broken swaps stay to prevent abuse, for 12 months from when the swap was broken.
Your rights
Under UK data protection law you can:
- Access your data: ask us for a copy.
- Correct it: edit your profile, or ask us.
- Erase it: Settings → Delete account, any time. It takes effect immediately.
- Take it with you (portability): email team@oxformals.com for an export.
- Restrict or object to how we use it.
- Withdraw consent: untick dietary sharing in your profile, or turn off notifications. This doesn't affect what we did before.
Email team@oxformals.comto use any of these. We reply within one month. If you're unhappy with how we handle your data, you can complain to the Information Commissioner's Office at ico.org.uk.
Cookies
We use only strictly necessary cookies: the sign-in cookies that keep you signed in, for up to 7 days. No analytics, advertising or tracking cookies, so there's no cookie banner. Fonts are served from our own site, not Google.
Age
Oxformals is for people aged 18 or over. We don't knowingly collect data from anyone younger; if you think we have, email team@oxformals.comand we'll delete it.
Changes
If we change this policy we'll update the date above. For significant changes we'll tell you by email or in the app first.
