The details

Privacy Policy

Last updated: September 2, 2026

TezBlock is built around a simple promise: your blocking choices stay on your device. Sign-in is optional and only needed for Friends and synced focus-session history. This document explains exactly what that means.

What TezBlock does NOT do

What stays on your device

The following data is stored locally on your iPhone. If you do not sign in, it is not sent to TezBlock's servers:

• Blocking profiles (which apps and websites you've chosen to block, schedules, settings)
• Focus session history and stats (session dates, durations, streaks, weekly totals, and activity heatmap data)
• 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.

What is shared if you sign in (optional)

If you choose to sign in for Friends and synced focus-session history, the following data is stored on our servers (Supabase):

• Account identifier (the internal user ID Supabase uses for your account)
• Display name (visible to your friends)
• Invite code (used to connect with friends)
• Session times (when you started and stopped focus sessions — used for friend activity and cloud sync)
• Profile name (the name of the blocking profile used, e.g. "Work Focus" — not which apps are blocked)
• Friends list (who you've added as friends via invite code)
• Session reactions (reactions you leave on friends' completed focus sessions)

We never store which apps or websites you block. That information stays on your device. You can delete your account and all associated data at any time from Settings.

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 a $9.99 one-time, non-consumable purchase through Apple's App Store. Apple processes the payment, not us. Apple shares with us only:

• An anonymous transaction ID
• The purchase and entitlement status needed to unlock and restore Pro access

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

The current Pro purchase does not renew, so there is no subscription to cancel. People who previously paid for a TezBlock monthly or annual plan keep permanent Pro access. During the transition, TezBlock may also check a current legacy entitlement so access is not interrupted.

Third-party services

The TezBlock app does not use any third-party analytics, advertising, crash reporting, or marketing services.

The network connections the app makes are:

• Supabase — only if you sign in. Used for authentication (Apple, Google, or email sign-in), synced focus-session history, and the Friends feature. Supabase stores the data described in the "What is shared if you sign in" section above. Supabase's infrastructure runs on AWS. Supabase Privacy Policy.
• Apple's StoreKit servers — to verify purchase and entitlement status. This is handled by iOS itself.
• NFC tag store 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.

Website and newsletter

The TezBlock website does not use advertising trackers. If you choose to subscribe to product updates, the email address you submit is sent to Loops, our email delivery provider, and used only to send the updates you requested. Newsletter data is separate from your TezBlock app data, is not sold, and is not used to determine which apps or websites you block.

You can unsubscribe using the link in any newsletter email. Loops processes subscriber information under its Privacy Policy.

Children's privacy

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