Privacy Policy — Clav

Version of 25.10.2026 · Alpine Lynx, Switzerland

In short

Clav does not collect data. Documents, names and keys stay on this iPhone, locked. There is no server, account, advertising or usage data. There is no analytics in the app either. On this website I only count clicks on the App Store buttons, without identifying anyone.

What leaves the iPhone

Only what you choose to send: a locked .clav file (a share or a backup) or an unlocked copy. Clav does not know where it goes.

The person code you show to add someone carries your name and your public key. It opens nothing on its own.

Camera, microphone and Photos

Camera. To scan documents, take photos and record videos that go straight to the vault, and read another person's code or the QR code on the security card. The images never leave this iPhone.

Microphone. Only to record the sound of videos you film inside Clav. The sound never leaves this iPhone.

Photos. Only to delete from Photos the original of a photo or video you have already locked in the vault, when you ask. Clav does not read your other photos.

Choosing a photo or video from Photos needs no permission: the iPhone only hands Clav what you pick.

Your key

Keys are kept in this iPhone’s Keychain, with the setting “this device only”. They never go to iCloud, and a backup cannot restore them on another iPhone.

Purchases

Purchases go through Apple. Alpine Lynx does not receive your name or payment details.

This website

This site sets no cookies and runs no tracking scripts. It is served by my hosting provider, which may keep standard technical logs (such as IP addresses) to operate the service.

When you tap an App Store button on this site, the link first goes through alpinelynx.ch/go/ and then opens the App Store. I count these clicks to know which pages help people find the apps. For each click I keep only the app, the page of alpinelynx.ch it came from and the date and time: no IP address, no cookie, no browser details, nothing that identifies you. These records are deleted automatically after three months; after that I keep only daily totals.

Your rights

Because Alpine Lynx keeps none of your data, there is nothing to request, correct or erase at Alpine Lynx. To erase everything on this iPhone: Settings › Privacy and data › Erase all data.

Children

Clav is not directed at children under 13.

Changes

If this policy changes, the new version will be published on this page with a new date.
