Privacy Policy

Last updated: April 12, 2026

TezBlock is built around a simple promise: your data stays on your device. This document explains exactly what that means.

What TezBlock does NOT do

• No account. You don't sign up. You don't give us your name, email, or password.
• No tracking. We do not use analytics, advertising IDs, or third-party trackers.
• No data collection. TezBlock does not send your usage, blocked apps, focus sessions, or any personal information to any server.
• No ads.

What stays on your device

Everything TezBlock stores is kept locally on your iPhone:

• Blocking profiles (which apps and websites you've chosen to block, schedules, settings)
• Session history (when you started and stopped focus sessions, used for the activity tracker on the home screen)
• NFC tag and QR code identifiers (only if you've configured a "physical unblock" tag — these are stored as local references, not uploaded anywhere)
• Theme and app preferences

This data is stored using Apple's standard SwiftData framework and lives only on your device. It is included in your iCloud device backup if you have iCloud Backup enabled — but that backup is encrypted by Apple and TezBlock has no access to it.

Permissions TezBlock requests

• Screen Time / Family Controls. Required to block apps and websites. This permission is processed entirely on-device by Apple's framework. TezBlock never sees the names of the apps you block (Apple represents them as opaque tokens).
• NFC. Required only if you use NFC tag features. NFC reads happen on-device and are not transmitted anywhere.
• Camera. Required only if you use QR code features. Camera input is processed on-device for code scanning and is never recorded or saved.
• Notifications (optional). Used only to remind you about active focus sessions.

In-App Purchases

TezBlock Pro is sold as an auto-renewable subscription via Apple's App Store. Apple processes the payment, not us. Apple shares with us only:

• An anonymous transaction ID
• Whether you currently have an active Pro subscription

We do not see your name, email, billing address, or payment method.

You can manage or cancel your subscription at any time in the iOS Settings app under your Apple ID → Subscriptions.

Third-party services

TezBlock does not integrate with any third-party analytics, advertising, crash reporting, or marketing services.

The only network connections the app makes are:

• Apple's StoreKit servers — to verify subscription status. This is handled by iOS itself.
• App Store search links — when you tap the "Buy NFC Tags" links in Settings, you are taken to Amazon, Temu, or AliExpress in your default browser. Once you leave TezBlock, those companies' privacy policies apply.

Children's privacy

TezBlock is not directed at children under 13. It does not knowingly collect any information from children.

Changes to this policy

If this policy changes, the new version will be posted at the same URL with an updated "Last updated" date.
