This is a plain-language draft. It has not been reviewed by a lawyer yet and is not the final legal text. Legal counsel will check it before launch.
Coinkin keeps as little personal data as it can. This policy explains what we collect, where it goes, how long we keep it and the choices you have.
1. What you tell us
Your money set-up (income, payday, bills, goal and balance) and your purchases are typed or spoken by you. We never ask for or store your bank login, card numbers or account numbers.
2. Your account
For your account we keep your email address and, if you give it, your first name, plus your language, country and plan. Your password is handled by our sign-in provider (Supabase) and is never stored in the app.
3. Where your data is stored
Your data is stored on your device. When you are signed in to an account, it is also synced to our servers in the European Union (Frankfurt), so it follows you to a new phone. A local demo account keeps everything on the device only.
4. Receipts and photos
When you scan a receipt or a price tag, the image is sent to be read for its items and prices. Coinkin does not store the image at all: only the items and prices you choose to keep are saved.
5. Voice
When you talk to a character, turning your speech into text is done by your phone’s own speech service. In a live voice conversation your voice is sent to Google Gemini so the character can answer. Coinkin does not store your recordings. Transcripts are kept only if you leave conversation history on. The characters’ spoken lines can be kept as shared clips for reuse; they never carry a link to you.
6. Shared prices
If you agree, prices read from your receipts join a shared price list that helps everyone get better price checks. It holds only the store, product, price and time, never anything that identifies you. It is off unless you turn it on, and you can change it any time.
7. Service providers
We use these providers to run Coinkin: hosting, database and sign-in: Supabase. Reading receipts and wording the characters’ replies: OpenAI. Character voices and live voice: Google Gemini. Price search: SerpApi and Firecrawl. Push notifications: Expo, delivered through Apple and Google. Requests to the AI providers carry no names, emails or account identifiers.
8. Price alerts
If you turn on alerts, a push notification tells you about an item you track, for example its new price or that it is back in stock. Alerts never contain your balance or income. To deliver them we keep your device’s notification token, language, country and time zone.
9. Security
Data travels encrypted between the app and our servers. On our servers each account can read only its own records. Protect your phone with a lock screen, because the data on the device is only as safe as the device.
10. What we do not do
We do not sell your data and we do not show third-party ads based on your money. We use your data only to run Coinkin for you.
11. Your choices
You can edit your data in the app at any time. “Download my data” in your profile gives you a copy in one file. You can turn off price sharing, notifications and conversation history. “Delete my account” removes your account and your records from our servers and wipes the app on your device.
12. How long we keep data
Your account data is kept until you delete your account. Sign-ups whose email is never confirmed are removed after 7 days. Usage logs lose their link to your account after 90 days. Shared voice clips that are not used for 90 days are removed, and they never carry a link to you.
13. Age
Coinkin is for adults. You must be 18 or older to create an account.
14. Who we are, contact and changes
Coinkin is run by [company name and address to be added before launch]. For privacy questions or requests write to [contact email to be added before launch]. You can also complain to a data protection authority: [supervisory authority to be added before launch]. If this policy changes in a way that matters, we will tell you in the app first.
