Privacy Policy · Privacy details

Lessons, translations, search, calculators and saved progress work on your device. This app has no account system, advertising or analytics. When you consent and send a tutor question, the question, selected lesson context and a short recent conversation are sent over HTTPS through ULTIMATE DIGITAL to OpenAI. For ordinary tutor requests, our database does not store questions, answers, photos, raw purchase receipts or raw IP addresses. The server stores purchase hashes, entitlement status, request identifiers and usage counters. Temporary request and usage records are retained for up to 93 days; network rate-limit hashes for up to 7 days. Active purchase hashes are retained to verify access. Server hosting and network providers process technical connection data under their own policies. Conversations stay in memory until reset or the app closes. You can withdraw AI consent in About the app. Withdrawing consent stops new question requests; it does not cancel a subscription or delete content already processed by OpenAI. Clear app data or uninstall to remove locally saved preferences and progress.

Children may use the handbook and offline exercises. The cloud tutor is available only to adults aged 18 and over who declare their age on this device and separately consent to sending questions. This is a self-declaration, not verified identity. The date of birth is checked locally, then discarded; it is not saved or sent. Only an adult or restricted profile and the policy version are saved on the device. An adult eligibility declaration and policy version accompany tutor requests; no date of birth is included. Underage and skipped profiles cannot send questions or use the cloud tutor. Withdrawing AI consent does not reset the age profile. Pro does not override the age restriction.

If you redeem an access code supplied by ULTIMATE DIGITAL, the code is sent over HTTPS to our server for verification and is not saved on this device or in our database. The device saves a signed access credential valid for up to 30 days and verified access metadata cached for up to 3 days for offline use. The server stores a hashed license identifier and access status. Access can be revoked; cloud access is checked on every question. Removing code access deletes the saved credential and its local access metadata. Code access never overrides the tutor age restriction or question limits.

If you send a report, this answer and the selected reason are sent to ULTIMATE DIGITAL for review and stored for up to 31 days. Your question and the rest of the conversation are not included.

Google Play processes payments. We do not receive your card or bank details. Our server checks the purchase receipt with Google and stores a hash of the receipt, the purchased product and its status to verify Pro and enforce tutor limits.

For adults aged 18 and over only. Your question, selected lesson text and recent conversation will be sent through ULTIMATE DIGITAL's server to OpenAI to generate a reply.

Internet and Pro are required. AI can make mistakes; check its answers. Up to 20 questions per day and 500 per month. You can withdraw consent in About the app.
