Privacy Policy
Last updated: July 2026
Libre is built privacy-first. The app has no account, no advertising, and no third-party tracking. This policy explains exactly what the Libre app collects — and what this website uses when you visit or buy the device.
No account, no profile
Libre does not require you to create an account or sign in. Your device is identified only by a random, app-generated ID. We never ask for your name, contacts, or location.
What we collect
A random device identifier and your NFC device’s hardware serial number, used to pair your device and keep your lives count and focus history consistent across reinstalls.
An email address — only if you choose to enter one to contact support.
Support messages — only the free-text you choose to send us.
Focus-session telemetry: timestamps, the reason a session ended, and the number of apps you blocked. This is used for your stats, streaks, and bypass detection.
What we can never see
Libre cannot see which apps you block. Apple’s app picker returns opaque tokens that, by design, no one — including Libre — can decode. Only the count of blocked apps ever leaves your device.
Libre cannot read your screen, keyboard, microphone, camera, messages, passwords, contacts, or location.
No tracking, no ads — in the app
The Libre app runs no advertising, no third-party analytics, and no tracking SDKs. It does not track you across apps or websites, and we do not sell or share your data.
This website: analytics & purchases
With your consent, this website uses Google Analytics 4 and the Meta pixel to understand which campaigns bring visitors and how our advertising performs. These tools set cookies and receive standard technical data (pages viewed, device type, approximate location). If you decline the banner, they never load.
The site also remembers in your browser (localStorage) how you arrived — campaign parameters such as utm_source and the referring site. If you buy, that information is attached to your order so we know which campaign led to the sale. If you accepted analytics, your Google Analytics client identifier (a random cookie ID) is attached as well, so we can connect the sale to its campaign in our analytics. None of this is used to profile you or shared beyond the order record.
Purchases are processed by Shopify (our store platform) and Mercado Pago (payments). They receive what is needed to fulfill your order: name, shipping address, email, and payment details. Card data goes only to the payment processor — we never see it. Their own privacy policies apply to that processing.
You can change your choice at any time via “Cookie preferences” in the footer — the banner will ask again.
How your data is protected
Sensitive identifiers are stored in the iOS Keychain. All communication with our server uses HTTPS, with certificate pinning to a fixed set of trusted root certificates.
Deleting your data
You can delete all of your data at any time from Profile → Danger Zone inside the app. This permanently removes your device record and associated data from our server.
