Privacy policy

Short version: we translate what you ask us to translate, we keep saved chats only if you save them, they're encrypted, and you can delete everything at any time. We never sell your data and never use it to train AI.

Your account

When you open the app we create an anonymous account: a random ID and a secret key stored on your device. We don't ask for your name, email or phone number. If you choose Sign in with Apple, we store only a one-way hash of Apple's user ID (not your email) so you can use the same account on another device.

Text you translate

When you tap Translate, Write, Explain or Ask, the text is sent over an encrypted connection to our server and to our AI provider (Google Gemini, paid API) to produce the answer. We don't store this text. Google's terms for the paid Gemini API say this data isn't used to train their models.

Saved chats (Remember)

• A chat is saved only when you import it and tap Save.
• Messages, names, facts and summaries are encrypted (AES-256-GCM) with a key unique to your account before they're stored.
• You can pause memory, delete a chat, or delete your whole account from the app. Deleting removes the data from our database at once.
• Saved chats are never used to train AI and never shared.

Keyboard and notifications (optional)

The Smartlation keyboard sends text only when you tap one of its buttons; everything else you type stays on your phone. On Android, if you switch on "Translate chat notifications", incoming chat notifications that aren't in your language are sent for translation and shown back to you; nothing is saved.

Telegram reminders (optional)

If you connect Telegram, we store your Telegram user ID to send you reminders and change alerts. Disconnect any time in the app.

The Telegram bot

Messages you send to the bot, and messages in groups where the bot translates, are sent to our AI provider to translate them and are not stored. We keep your Telegram ID with your settings (language, style, gender) and your plan.

Private assistant (optional, Premium). If you switch the assistant on for a group, the messages in that group from that moment on are saved, encrypted, for you only, so the assistant can tell you about changes, agreements and unanswered questions. Only you receive its messages. Turn it off or delete everything saved from a group at any time with /assistant. Messages you forward to the bot for advice are not stored.

Payments

App Store purchases are handled by Apple, PayPal payments by PayPal, and PromptPay transfers by your bank. For PromptPay payments in the Telegram bot, the payment slip you send is checked with a slip-verification service (Thunder) to confirm the transfer; we keep only the transfer reference, amount and date. We never see card details; we only store which plan you have and until when.

Technical data

To stop abuse we count usage per account and per connection. IP addresses are stored only as one-way hashes. Our servers run on Cloudflare.

Your rights

Under Thailand's Personal Data Protection Act (PDPA) and similar laws you can ask what we hold, and have it corrected or deleted. Most of this you can do yourself in the app (Account → Delete account). For anything else, email benkawth@gmail.com.

Children

Smartlation is not meant for children under 13.
