Privacy Policy — BirthdayDeals mobile app
Last updated: 28-07-2026
This policy covers the mobile app specifically. For the website, see our general privacy policy.
1. Who we are
BirthdayDeals offers free birthday deals through a website and a mobile app. This policy explains what data the app collects, why, and how long we keep it.
2. What data we collect
When you create an account
- Name — for personalisation and how we address you (required)
- Email address — to sign in and communicate with you (required)
- Date of birth — the core function: showing deals around your birthday (required)
- Country and city — to show deals in your region (required)
- Language preference — to show the app in the right language (required)
- Parental consent and parent's email address — only for users under 16
Automatically while using the app (diagnostic, first party)
- Device model, make, operating system and version — for support and troubleshooting
- App version, language, time zone and screen size — to display the app correctly
- Network type (wifi or mobile), battery status and memory class — to diagnose performance and loading issues. This is a snapshot, not continuous tracking
- How often the app was opened and when you were last active — for support
- A device identifier provided by the operating system (the "identifier for vendor" on iOS, the Android ID on Android) — to recognise your device for support and to prevent duplicate registrations. This identifier cannot be linked to other apps and is not an advertising ID
- On Android: how the app was installed (the install referrer) — to see which link or campaign brought you to us
- Push token, only if you allow notifications — to send birthday reminders
Activity in the app
- Deals you viewed — for more relevant recommendations
- When you open and close the app (session length), linked to a session ID — to understand how the app is used
- Saved favourites — so you can find deals again
- Claimed deals and their voucher or claim codes — to redeem your gifts on location
- Ratings (stars) — for deal quality
- Friends you referred — for chances at the main prize
Crash and performance data
When the app crashes we automatically send technical error data (via Sentry) to improve the app. This contains no messages or passwords.
What we do not collect
No precise GPS location, no advertising ID, no access to your contacts and no access to your calendar.
3. Anonymous use before registration
When you first open the app we create an anonymous profile so you can browse deals and save favourites straight away. Once you register, this anonymous profile becomes your account — the favourites and viewed deals you saved earlier are kept. We never sell this data and never share it with advertisers.
4. Who we share data with
- Supabase (hosting and database, EU) — storage of your account and data
- Sentry (crash reporting, EU) — technical error data
- Brevo and Resend (email) — sending transactional and birthday emails
- Participating businesses — only see that you claimed a deal (name and deal) when you redeem it on location; no other data
We never sell your data to third parties.
5. How long we keep data
- Account and activity: as long as your account is active. After deletion your personal data is removed or made unidentifiable.
- Fraud prevention: after deletion we keep your claim history for a maximum of 12 months under an encrypted email hash, so that deleting and re-registering cannot bypass the free-claim cooldown.
- Security logs: a few months, solely for fraud detection.
6. Your rights
You can view and correct your data and delete your account entirely — directly in the app under Settings. You have the right to access, rectification, erasure and data portability (GDPR).

7. Children
For users under 16 we ask for parental consent at registration. The date of birth you provide must be realistic.
8. Changes
We may update this policy. The date at the top shows the most recent change.
