Privacy Policy

Tysh is operated by So Nerdy LLC. In this policy, "Tysh," "we," "us," and "our" refer to So Nerdy LLC and the Tysh app and website.

You can contact us about privacy at dima@sonerdy.me.

Tysh helps you create focus sessions, scheduled blocks, launch budgets, and discipline scores using Apple Screen Time technologies. Tysh is designed so detailed Screen Time and app usage activity stays on your device and is not stored by So Nerdy LLC in Firebase or another server.

If you use Tysh without an account, the app stores your focus setup and Screen Time-related activity locally on your device.

If you sign in, Tysh uses Firebase Authentication and may process your email address, display name, authentication provider, Firebase user ID, and related sign-in information. If you use Sign in with Apple or Google Sign-In, those providers may also process information according to their own policies.

Tysh syncs a limited set of account data with Firebase Firestore so you can back up and restore your setup. This may include block list names and app counts, scheduled block names, days, times, enabled state, and protection mode, launch-budget settings, app settings such as default focus duration and daily focus goal, discipline-day scores, timestamps, deletion markers, and a random device identifier used for sync.

If you contact us, we collect the information you choose to send, such as your email address and message.

Tysh does not store detailed app usage, Screen Time reports, top apps, pickups, notifications, hourly usage, shield events, focus-session history, or detailed app/category selections in Firebase.

App and category selections are handled through Apple's Screen Time APIs. Selection tokens are stored locally and may be stored in Apple Keychain or Apple-managed sync where enabled by your device settings, but they are not uploaded to Tysh's Firestore database.

The website at ty.sh uses Vercel Analytics to understand aggregate website traffic, such as page views, referrers, browser, device, and performance information. We use this information to improve the website. The Tysh iOS app does not use advertising SDKs and does not use third-party advertising tracking.

• To create and manage your account.
• To sync and restore your Tysh setup across installs or devices.
• To provide app functionality, support, maintenance, and security.
• To respond to messages you send us.
• To comply with legal obligations and enforce our Terms.

Tysh subscriptions are processed through Apple's in-app purchase system. Apple handles your payment information. We do not receive your full payment card number. We may receive subscription status or transaction information needed to provide paid features, manage access, and support purchases.

We do not sell your personal information. We do not share your information for third-party targeted advertising.

We use service providers to operate Tysh, including Firebase Authentication, Firebase Firestore, Google Sign-In, Apple's sign-in and in-app purchase services, and Vercel for the website. These providers process information for us or provide platform services needed to run Tysh.

We may also disclose information if required by law, to protect rights and safety, or in connection with a merger, acquisition, financing, or sale of assets.

Local app data remains on your device until you delete it in the app, delete your account, uninstall the app, or your device removes it.

Cloud sync data is retained while your account is active or as needed to provide sync, support, security, and legal compliance. You can delete your account in the app. You can also request deletion of your Firebase account and cloud sync data by emailing dima@sonerdy.me.

Some data may remain in backups, logs, or records for a limited period when required for security, legal compliance, or dispute resolution.

You can use Tysh without creating an account. You can stop cloud sync by signing out. You can manage Screen Time permissions in iOS Settings. You can manage or cancel subscriptions through your Apple ID settings.

Depending on where you live, you may have rights to access, correct, delete, export, restrict, or object to certain processing of your personal information. To make a request, contact dima@sonerdy.me.

Tysh is operated from the United States and uses providers that may process information in the United States and other countries. If you use Tysh from outside the United States, your information may be transferred to countries with different data protection laws than your country.

Tysh is not directed to children and is not in the App Store Kids Category. Tysh is intended for users age 13 and older. If you are under the age of majority where you live, use Tysh only with permission from a parent or guardian.

We use reasonable technical and organizational measures to protect the information we process. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

We may update this Privacy Policy from time to time. If we make material changes, we will update the date above and may provide additional notice in the app or on the website.
