Data we process
- Account: e-mail and sign-in data (also via Apple or Google) – visible only to you.
- Profile: first and last name, status (e.g. Dad, Mum), phone, address – family members see your status and first name; the rest only you.
- Payment details: bank account, variable symbol, payment note – used for QR payments; visible to you and the adults of your family.
- Family members: children's first names and birth years, statuses of close persons.
- Payments: expenses, alimony, settlements, edits and their history; receipt photos – visible to the adults of your family.
- Settings: expense and reminder settings, device token for push notifications.
No ads, no analytics, no tracking across apps or websites. We do not sell data or share it for marketing.
On your phone
Receipt reading (amount, date, shop) runs on the iPhone. Dictation uses Apple's speech recognition; audio is processed by Apple under its policies, and Wlny stores only the resulting text you confirm.
Where data is stored and who helps us
- Supabase – database, sign-in and photo storage, servers in the EU (Ireland).
- Apple – Sign in with Apple, push notifications, speech recognition.
- Google – only if you sign in with Google.
AI assistant (optional)
In Settings → AI assistant you can connect an AI assistant of your choice (e.g. Claude). With your consent, the assistant holding your personal link can read your family's expenses, alimony and settlements and record your payments. The assistant provider's terms apply to its processing. You can turn it off at any time, which disables the link. We store only a hash of the key.
Legal basis
Performance of the service you use (Art. 6(1)(b) GDPR); notifications and the AI assistant are based on your consent (Art. 6(1)(a) GDPR), which you can withdraw by turning them off.
Children
Children's data is entered by parents. A child can get an account only by a parent's invitation; a child's account does not see payments, alimony or payment details.
Retention and deletion
For as long as you use the app. You can delete your account in Settings → Delete account. We delete your profile, contact details, address, payment details, notification devices and AI key. Payments you recorded remain for the other family members as their shared record, with the author shown as "Former member".
Security
Encrypted transport (HTTPS); row-level access rules in the database so everyone sees only their own family's data; receipt photos in private storage.
Your rights
Access, rectification, erasure, restriction, portability (export the full history as CSV in the Overview) and objection – write to the e-mail above. You may also complain to the Czech Office for Personal Data Protection (uoou.gov.cz).
