1. Information We Collect
No account. There is no sign-up, no login and no account of any kind. The app contains no advertising.
- Coin photos you choose to identify. When you tap Identify, the photo(s) of the coin you took or picked
(front, and back if you add it) are sent over an encrypted connection to our identification server, which passes them to
an AI model (Google Gemini API) and returns the result. We do not store your photos on our server —
they are used for that single identification and then discarded. Please photograph only the coin.
- Daily usage counter. To apply the free daily limit, our server keeps the number of identifications per day
for a random install identifier the app generates. It contains no name, e-mail, device identifier or advertising ID.
- Purchase check. If you have CoinLoupe Pro, the app sends your Google Play purchase token so our server can
confirm the purchase with Google and lift the limit. We store only a one-way hash of that token and its status.
- Anonymous usage events. A fixed, minimal set of anonymous events (first launch, scan screen opened, camera permission allowed or declined, identification requested and its outcome (success, not a coin, error), sample coin opened, first successful identification,
whether the plan screen was shown and from which screen, purchase started / completed / cancelled / failed, restore, the first time a result is closed after a successful identification, whether a review prompt was requested,
that a result card was shared (not what or with whom), that the link to our other app in Settings was tapped, and a
"still installed" ping on day 1 and day 7). A shared card's store link carries only a fixed campaign tag (utm_source=share), never coin details. Each event carries only the random install identifier, an app tag, the event name
and a timestamp. Raw events are kept for up to 90 days, then only aggregate counts remain.
- No advertising identifier is requested or used. No ad, analytics or crash-reporting SDK is present.
2. Where Your Data Lives
| Data | Purpose | Stored |
|---|
| Your collection: coin photos, identification results, notes, quantities | Your collection and history | On your device |
| Photos sent for identification | Identifying the coin | Not stored by us — processed and discarded |
| Daily identification count (random install identifier) | Free daily limit | Our server |
| Hash of Pro purchase token and its status | Unlocking Pro on our server | Our server |
| Anonymous usage events | Seeing where people drop off | Our server — raw events up to 90 days, then aggregates only |
Camera. The camera is used only while the scan screen is open, to take the coin photo you choose to identify.
You can also pick a photo instead; the system photo picker gives the app only the photo you select.
Backup. Android's built-in app backup may copy your collection to your own Google account backup if you have it enabled;
that is governed by Google. A CSV export (Pro) goes only where you send it.
3. Third-Party Services
- Google Gemini API — the AI model that reads the coin photo. Google processes the photo as our service provider
to return the result and does not use it to train its models under the paid API terms. See the
Gemini API Additional Terms.
- Cloudflare — hosts our identification and usage servers.
- Google Play Billing — in-app purchases and subscriptions are processed entirely by Google. We never see your payment details.
Subscriptions are managed and cancelled in Google Play.
Google's handling of data is governed by the Google Privacy Policy.
4. Overseas Transfer of Personal Data
Coin photos you submit are processed on Cloudflare and Google infrastructure, which may be located outside your country.
They are transferred at the moment you tap Identify, over an encrypted connection, only to identify the coin, and are not retained by us.
5. Values Are Estimates
Identifications and value ranges are AI estimates for information only. They are not appraisals or offers to buy, and actual
prices depend on condition, authenticity and the market. Consult a professional before buying or selling.
6. Advertising and Tracking
- No ads. The app displays no advertising of any kind.
- No tracking. Nothing about you is tracked across apps or websites.
7. Age
This app is not directed at children under 13.
8. Your Rights
- Collection — delete any coin in the app; deleting the app removes all local data.
- Server data — the daily counter and anonymous events cannot be linked back to you; send us your request and we will help where we can.
