Sillage privacy policy

Last updated 03 September 2026

Sillage collects nothing. This page explains what that means in practice.

What is collected

Nothing. Sillage does not collect, transmit, sell or share any personal information. There is no account, no sign-in, and no server that belongs to us.

Where your data lives

Every entry, anchor line, note tag, bottle, wear, drill result and setting is written to this device's private app storage. Nothing is uploaded, nothing is backed up to us, and nothing is shared. Uninstalling the app deletes all of it, which is why Sillage can export the whole notebook as JSON or CSV at any time from Settings, and can erase everything in two taps.

Network

Sillage does not request the INTERNET permission. It cannot send your data anywhere, because Android will not let it open a network connection at all. This is verifiable in the app's manifest on the Play listing.

Permissions

Children

Sillage is not directed at children under 13 and collects nothing from anyone, of any age.

Analytics, ads and tracking

There are none. Sillage contains no advertising SDK, no analytics SDK, and no crash reporter. It does not use an advertising ID.

Your rights

Because nothing is collected or transmitted, there is nothing held about you to access, correct or delete on a server. Uninstalling the app removes its data from your device. Any in-app export gives you a copy of your own content in an open format.

Your camera and your photographs

Sillage has no camera permission and no photo picker. It cannot open the camera and it cannot read your gallery. The bottles on your shelf are drawn in code from the name and the notes you typed, which is why every shelf looks different without a single photograph being taken.

Your location

There is no location permission. The place on an entry is a line of text you typed, nothing more. The hemisphere setting is a two-way switch you choose yourself, used only to decide whether October is autumn or spring for you.

The internet

Sillage does not request the INTERNET permission, so Android will not let it open a connection even by accident. There is no account, no sync, no analytics, no crash reporter and no advertising identifier. You can confirm the permission list on the Play listing before you install.

Notifications

Reminders are scheduled on the device through Android's alarm manager. No push service is involved and no message travels over a network. If you turn reminders off in Settings, the whole schedule is cancelled.

Prices on your shelf

If you record what a bottle cost, that number stays on the device with everything else and is used only to work out cost per wear. Settings has a switch that hides prices on screen for when you hand your phone to somebody.

Export and import

Exporting writes a plain file into this device's Downloads folder using your own tap. It is not encrypted, so treat it the way you would treat a diary. The file leaves the device only if you choose to send it somewhere yourself. Importing reads a file you pick and merges it into what is already here.

Analytics

There are none, opt in or otherwise. Sillage does not count how often you open it, how many entries you write or how well you score. It has no way to tell us anything, because it has no network permission at all.

Training is a hobby, not a treatment

The drills in Sillage are written as skill practice for people who want to smell better, in the same spirit as ear training or wine tasting. They are not a medical programme and the app makes no claim about smell loss or recovery. If you have lost your sense of smell, or it has changed suddenly, please speak to a doctor rather than an app.

Changes

If this policy changes, the updated version will be published at this address with a new date.
