Rucksack reads one number from your phone, the step counter, and keeps it here. It has no internet permission, so it could not send that number anywhere even if it wanted to.
Nothing. Rucksack does not collect, transmit, sell or share any personal information. There is no account, no sign-in, and no server that belongs to us.
Everything Rucksack knows lives in this device's private app storage: the daily step counts it has read, the kilometres they converted to, the camps you have made, the people you have met and the name you gave your wanderer. None of it is uploaded, and there is no account to attach it to. The app can write the whole record out as plain text or JSON whenever you ask, which is the only way any of it leaves the phone.
Rucksack 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.
Rucksack is not directed at children under 13 and collects nothing from anyone, of any age.
There are none. Rucksack contains no advertising SDK, no analytics SDK, and no crash reporter. It does not use an advertising ID.
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.
Rucksack does not declare the fine or coarse location permission and does not use GPS. It does not know which country you are in, let alone which street. The distance you travel across the map is arithmetic on a step count, nothing more.
The rain, mist and frost at your camp belong to Elsewhere, not to the place you are standing. It is worked out from the date and the region your wanderer is in, which is precisely why the app needs neither a forecast service nor your position.
Android's step counter reports one number: how many steps the phone has counted since it last started up. Rucksack reads that number when you open the app, works out how much is new since the last reading, and adds it to today. It cannot see a route, a speed, a time of day or an activity type, because the sensor does not report any of those things. If the phone restarts, the steps taken between the restart and the next time you open the app are simply lost, and the app says so in the ledger rather than guessing.
The app declares allowBackup="false", so Android does not copy your journey into Google Drive and does not carry it across in a device-to-device transfer. Moving a crossing to a new phone is the JSON export, which you do on purpose.
There is no sign-up, no email address and no profile. Nothing in the app is for sale, so there is no payment processor and no purchase history either. The journey belongs to the phone it was walked on.
If this policy changes, the updated version will be published at this address with a new date.
