Privacy — Tanica

Last updated 7 October 2026

The principle

Tanica downloads every price in the country you are in and does the arithmetic on your phone, so our relay never learns where you are. Apple Maps is the honest exception, and this page says exactly what it receives. We never receive, store or see any of your data. There is nothing for us to sell, lose or hand over, because there is nothing on our side to begin with.

What the app keeps

Tanica records what you put into it:

• your vehicles, your favourite stations, your saved places and your price alerts
• the last set of prices received, so the app and the widgets open on something
• your last position, kept on the device so the widgets can rank without waking the app

Where it lives

On your device. If you turn iCloud on, it also syncs through your own private iCloud database, which Apple encrypts and which we cannot open, read or list. We have no key and no access of any kind.

What it asks permission for

Every one of these is optional. Refuse any of them and the rest of the app keeps working.

Location, while the app is open

To rank the stations around you and along your route. During a trip the app keeps a location session open so the live activity stays right, and iOS shows the blue indicator the whole time. Your position is never sent to us.

Notifications

Only if you set a price alert. The phone checks in the background, at most once an hour, and the alert is delivered from the device itself.

What leaves the device

The app has no analytics, no crash reporting, no advertising and no third-party kit of any kind. What it does send, it sends only to the services below, and only for what you asked it to do:

Our relay, tanica.nidello.ca

One request per country, for that whole country’s prices (the country you are in, recognised on the phone, and those of your favourites), plus one for the world averages and exchange rates. Each carries nothing but the name of the file and the fingerprint of the copy you already have — no position, no vehicle, no identifier, no account. The relay reads no parameter, keeps no log and stores nothing about anyone: what it holds is the current price list.

Our AI connector, tanica.nidello.ca/mcp

Only if you add it to an AI assistant yourself (it is not used by the app). The AI can then ask it the questions the app answers — stations and best fill-up near a place, regional and national averages, sources — and may send it the place you asked about. The coordinates are rounded to about 1 km as soon as they arrive, used for that one calculation and then forgotten: never stored, never logged, no account. When the AI cannot answer something, the connector notes it for us in general terms — the AI’s generic description, never a place or anything about you — and sends us a daily summary of these feature requests. What you say to the AI stays under its own policy.

Apple Maps

Receives your starting point, your destination, what you type in the search field, and the candidate stations, because that is what computing a route means. That exchange is between you and Apple.

The App Store

If you buy Pro, your device talks to the App Store, as it does for any purchase. We are told a sale happened; we are never told who you are.

None of it reaches us. We have no server in any of these paths, and we never receive a copy.

Prices come only from public bodies, each named in the app. In Québec: Régie essence Québec, Régie de l’énergie, which authorised their reuse in writing on 2 October 2026; Tanica is not mandated by the Régie de l’énergie, nor by the Government of Québec. Exchange rates come from the European Central Bank (and, for the Argentine peso, the Banco Central de la República Argentina; for currencies neither quotes, Narodowy Bank Polski).

Your data is yours

Export everything, whenever you want, without asking us. Delete the app and what was only on the device is gone; what synced to iCloud goes when you remove it from your iCloud settings. We cannot recover any of it for you, because we never had it.

Children

The app is not directed at children and collects nothing about anyone, of any age.

Changes to this page

If the app ever starts doing something this page does not describe, this page changes first. The date at the top says when it last did.

Your rights

Quebec’s Law 25 and similar laws elsewhere give you the right to access, correct and delete the personal information a business holds about you. In our case the answer is the same every time: we hold none. Your information is on your device and in your own iCloud, where you can already read, change and delete all of it yourself.
