Privacy Policy

The Short Version

• No Kappi account is required.
• Your app selections, blocking history, and Screen Time data stay on your device.
• We collect limited app analytics through PostHog, purchase data through RevenueCat, and ad attribution through Appstack when it is enabled.
• Apple processes all payments.
• We do not sell your personal data.

What Stays on Your Device

Apple gives Kappi private tokens for the apps and categories you choose. Kappi uses those tokens to apply your blocks, but cannot read the names of your selected apps. The tokens never leave your device.

Your blocking history and focus-session records also stay on your device. Kappi does not collect or send Screen Time usage reports or app usage durations.

What We Collect

App analytics

PostHog receives limited events such as onboarding starting, a focus session starting, or a blocked app being opened. These events may include:

• A random identifier generated on your device
• Device type, operating system, and app version
• Session start and end times
• Country or region inferred from network information

Analytics never include app names, web domains, Screen Time reports, or app usage durations.

Purchases

RevenueCat helps Kappi confirm subscriptions and provide Kappi Plus access. It receives purchase status, product identifiers, transaction dates, paywall events, device information, and the same random identifier used for analytics. RevenueCat does not receive your app selections or Screen Time data.

Emails and support

If you join the waitlist, Resend stores your email so we can send launch updates. If you contact support, we use the information you provide to reply.

Crash reports

If you share diagnostics with Apple, Apple may provide us with aggregated crash and performance reports. These may include your device model, operating system, app version, and crash details.

Attribution

In versions where advertising attribution is enabled, Kappi uses Appstack to measure installs and subscription events from ads. Kappi will ask for Apple's tracking permission before using an advertising identifier. If you decline, Kappi still works. Appstack may process device identifiers, device details, attribution data, session information, and the limited events we send. It never receives your app selections or Screen Time data.

Screen Time Permission

Kappi uses Apple's Family Controls, Managed Settings, and Device Activity frameworks to block apps. iOS, not Kappi's servers, enforces your blocks. You can revoke Screen Time permission in iOS Settings.

Service Providers

These companies process limited data for Kappi:

• PostHog for app analytics
• RevenueCat for subscriptions and purchase validation
• Resend for waitlist and support emails
• Appstack for advertising attribution when enabled
• Apple for Screen Time, payments, and optional diagnostic reports

Retention and Deletion

Deleting Kappi removes its local data from your device. Apple keeps purchase records for billing and fraud prevention. You can manage purchases through your Apple Account.

You can unsubscribe from waitlist emails at any time. You can also ask us to delete an email or support message by contacting us below.

Children

Kappi is not directed to children under 13 and is not a parental control product. If you believe a child has sent us personal information, contact us and we will delete it.

Your Privacy Rights

Depending on where you live, you may have the right to access, correct, or delete personal data we hold about you. Contact us to make a request. Your app selections and blocking history stay on your device and are already under your control.

Security

Kappi keeps sensitive app and blocking data on your device, protected by your device's passcode and encryption. No system is perfectly secure, but we limit the data sent to outside services.

Policy Changes

We may update this policy as Kappi changes. We will post the new policy here and change the date at the top of the page.
