Privacy Policy

1. Data we collect

• Account data: email address, name, password (stored only as a one-way hash), profile picture, your native language, English level and interests. If you sign in with Google, we receive your Google email, name and profile picture.
• Learning content: words and phrases you save, translations, your progress and review schedule, saved sentences, word chats and AI chats, and the books and page texts you add.
• Photos and text you submit: when you scan a book page, the photo or text is processed to extract text and words.
• Device and notification data: a push-notification token if you enable reminders, and your notification preferences.
• Technical data: standard server logs (time, request path, status, IP address) kept by our hosting providers to run and protect the service.

2. How we use it

We do not sell your personal data and we do not use it for advertising.

• To provide the app: save your words, translate and explain them, build training and games, and sync between the app, the website and connected assistants.
• To run AI features: your texts, words and chat messages are sent to AI providers to generate translations, explanations and replies.
• To keep the service safe, fix bugs and prevent abuse.
• To send emails you request (such as one-time codes and password resets) and notifications you turn on.

3. Who processes data for us

We use trusted service providers who process data only to deliver their service to us:

• Hosting and database: Railway, Vercel and Supabase.
• AI and translation: OpenAI and Google (Generative AI and Cloud Translate) — receive the text you ask ZIV to translate, explain or discuss.
• Sign-in: Google Sign-In, if you choose it.
• Email: Resend, for one-time codes and password resets.
• Notifications: Apple Push Notification service, through Expo.
• Telegram: if you link the ZIV Telegram bot, Telegram delivers your messages to us.

4. AI assistants and the ZIV connector

If you connect ZIV to an AI assistant (Claude, ChatGPT, Meta Muse or another), you sign in with your ZIV account and allow it to add words to your list. The connector only adds words; it cannot read, edit or delete your other data. The assistant’s company handles what you tell the assistant under its own privacy policy. You can disconnect at any time in the assistant’s settings. The connector is meant for people who meet the AI assistant’s own minimum age (for example, 13+ for ChatGPT and 18+ for Claude); it is not directed at children.

5. Retention and deletion

We keep your data while your account exists. You can edit or delete words and content in the app. When you delete your account, or ask us to by emailing support@ziv-tutor.app, we permanently delete it and the data linked to it within 30 days, except for what we must keep to meet legal obligations. Backups and logs are removed on their normal schedule.

6. Security

Data is sent over encrypted connections, passwords are hashed, and access to production systems is restricted. No system is perfectly secure, so please use a strong, unique password.

7. Your rights

Depending on where you live, you may have the right to access, correct, export or delete your personal data, to object to or restrict some processing, and to withdraw consent. Contact support@ziv-tutor.app and we will respond within a reasonable time.

8. Children and families

ZIV is made for learners of all ages, from 5 years old. Children under 13 (or under the age of digital consent in their country, which may be up to 16) may use ZIV only with the permission and supervision of a parent or guardian, who should create or approve the account. We collect only the data needed to run the app and never use children’s data for advertising. A parent or guardian can ask us at support@ziv-tutor.app to see or delete a child’s data at any time.

9. International transfers

Our providers may process data in countries other than yours. We rely on appropriate safeguards where the law requires them.

10. Changes

We may update this policy. We will change the date above and, for material changes, tell you in the app or by email.
