Privacy Policy

The short version

Your travel history stays on your device. Stamp Days has no server, no account, and no analytics. Country names come from Apple's own location services.

That last sentence is the reason this page does not claim that nothing leaves your phone. Working out that a coordinate is in Portugal means asking Apple, and that request goes over the network.

Who is responsible

Stamp Days is published by Mousa Amin Sharifi, who is the data controller for the app. Privacy requests are handled on his behalf by Applestan, the studio that runs this site, which is why the address below is the studio's and not his own.

Location, the one data type

Location is the only thing Stamp Days collects, and the App Store privacy label says exactly that: Precise Location, used for App Functionality, not linked to you, and not used for tracking. In practice:

• The app uses the significant location change service of iOS, which wakes it when you have moved a long way rather than following you continuously
• Each of those points is turned into a country name by Apple's reverse geocoder. The app keeps the country and throws the coordinate away
• Nothing about your position is written to a server of ours, because there is no server of ours
• There is no advertising identifier, no analytics SDK and no crash reporting SDK in the app

iOS asks for permission before any of this. The app requests "When In Use" first, behind a button you tap yourself, and only asks for "Always" afterwards. "Always" is what lets the day count carry on while the app is closed.

Apple's location services

Turning a coordinate into the word "Portugal" is done by CLGeocoder, which is part of iOS. Apple receives the coordinate in order to answer. That processing is Apple's, under Apple's privacy policy, and we neither see the request nor get a copy of it. We list it here because a privacy policy that skipped it would be wrong.

What stays on your device

Your countries, your visits with their entry and exit dates, any state you set by hand, and your settings live in the app's own database on the phone. They are not uploaded, not synced to an account, and not readable by us. They are included in your own iCloud or device backup if you make one, under Apple's terms rather than ours. Deleting the app deletes all of it.

The home screen widget reads the same local data through an app group on the device. Nothing is sent anywhere to draw it.

Using it without location at all

Manual mode turns automatic tracking off and lets you pick your current country from a list. With it on, the app reads no location data. You can also decline the location prompt outright and still use the map, the history, the backfill and the stats, entering your trips by hand.

Notifications and other permissions

Stamp Days asks for two things: your location, and, only if you use Import from Photos, access to your photo library. Both are described on this page.

It never requests notification permission and posts no notifications. There is no sign-in and no remote-notification capability. There is one in-app purchase, described below.

Importing your travel history from Photos

Stamp Days can rebuild years of travel from photos you have already taken. If you start an import, iOS asks for access to your photo library.

The app reads only where and when each photo was taken. It never asks for the images themselves, and it cannot see what is in them.

Nothing is uploaded. Turning those coordinates into country names is done on your iPhone against a map of country borders included in the app. Unlike everyday tracking, an import does not send anything to Apple's geocoder, because there would be far too many lookups.

Nothing is saved without you. You see the trips the app thinks it found and choose which to keep. You can remove every imported day afterwards from Settings, and only imported days are removed.

If you never use Import from Photos, the app never asks for your library.

Paying for Stamp Days

Stamp Days is free to use. Automatic tracking, the map, your history, day counts and the widgets are free, along with the first five visits you add by hand. A single one-off purchase adds Import from Photos, the statistics charts and unlimited hand-entered visits. There is no subscription and no trial that turns into a charge.

The purchase is handled entirely by Apple. We never see your card, your billing address or your Apple Account. To know whether you have bought the app, or downloaded it before the purchase existed, in which case it stays unlocked for you, the app reads Apple's own record of your purchase on the device. That record is not sent anywhere and contains nothing about you personally.

Children

Stamp Days is a general-audience travel utility. It is not directed at children, and it collects nothing that would identify a user of any age.

Your rights

Since the app keeps no personal data on our side, there is usually no account or record for us to look up. You still have the right under the GDPR to ask for access, correction, deletion or restriction of processing, to object to processing, to data portability, and to withdraw consent. Email the address above and we will answer within a month. You can also complain to a data protection authority, in particular in the country where you live or work.

To stop the app reading your location from now on, switch automatic tracking off in Settings, or withdraw the permission in the iOS Settings app. To remove everything Stamp Days holds, delete the app.

What the day count is not

Stamp Days infers a border crossing from your phone's movement, so the record it builds is a useful estimate and not proof of where you legally were. It gives no legal, immigration or tax advice. Check the count against the rule that applies to you, and correct any visit that looks wrong.

Changes to this policy

If a future version of Stamp Days changes what it collects, this page and the App Store privacy disclosure get updated before that version ships, and the date below changes with it.
