Privacy policy
Short version: Smartlation is a translation bot on LINE and Telegram. It sends what it translates to our AI provider and doesn't keep those messages (except short-lived caches, below). The private assistant (Telegram, Business plan) saves group messages only when its user switches it on for a group. We never sell your data. You can delete your data any time by sending /deletemydata to the bot.
Who we are
Flex Shell CO., LTD. (Benkaw Group), Thailand — the data controller. Contact: office@benkawgroup.com.
What we keep about you
- Your LINE or Telegram user ID, display name (and Telegram username) as the app sends them, and your settings (language, Thai style, gender, language pair).
- Your plan, its dates, and records of your payments (payment reference, amount, date, method).
- Usage counters (how many translations, voice messages etc. per day) — to apply the daily limits and stop abuse.
- How you found us (an ad, the website or a friend's invite link), whether you took the free trial, and invite rewards.
- The groups the bot is in and their settings. On Telegram also which members wrote there recently (kept 60 days), so the assistant can list your groups.
- Ideas and problem reports you send with /feedback or the 🐞 button (including the text of the message that failed), so our team can fix things. They are sent to our team in Telegram and by email.
Messages you translate
Text and voice messages you send to the bot, messages in groups where it translates, and (on Telegram) text you type with @SmartlationBot in other chats are sent over an encrypted connection to Google Gemini (paid API) to be translated. Google doesn't use paid-API data to train its models. We don't store translated messages in our database. To make the bot fast, a translation can stay in a temporary cache for up to 24 hours, and on Telegram the bot remembers which of its replies belongs to which message for 7 days so it can follow edits. Questions you ask with "?" are answered the same way and not stored.
Private assistant (Telegram, Business plan, optional)
When a Business user switches the assistant on for a group, the messages in that group from that moment on (text, sender's name, time) are saved for that user, encrypted (AES-256-GCM), so it can point out changes, contradictions, agreements and unanswered questions to them privately. Only that user receives its messages; the bot doesn't post them in the group. It stops when they switch it off, when their plan ends, or when they leave the group. Notes can be deleted any time with /assistant or /deletemydata. Messages you forward to the bot for advice are not stored.
Payments
In Telegram you pay with Telegram Stars — Telegram, Apple or Google handle the payment; we receive only a payment reference. On smartlation.app you log in with LINE or Telegram and can pay by bank transfer to Kasikorn Bank (KBank): the slip picture is checked by a slip-verification service (Thunder; EasySlip as backup) and we keep the transfer reference, amount, date and your LINE or Telegram ID. PayPal and card payments are handled by PayPal — we never see card details.
Who processes data for us
LINE / LY Corporation (messaging and LINE Login), Telegram (messaging, Stars), Google (Gemini AI), Cloudflare (servers, database, email), PayPal, Thunder / EasySlip (slip checks). Some of them process data outside Thailand.
How long
Settings and usage: until you delete them. Payment records: as long as Thai accounting and tax law requires. Assistant notes: until you delete them or switch the assistant off and delete. /deletemydata removes your settings, usage, assistant notes, invite information and the words of your feedback reports. We keep your payments and plan (so a plan you paid for keeps working), any balance or top-up you have, and a note that you already used the free trial or first-month price, to prevent abuse.
Your rights
Under Thailand's Personal Data Protection Act (PDPA) you can ask what we hold, have it corrected, or deleted. Send /deletemydata to the bot to delete your data yourself, or email office@benkawgroup.com.
Age
Smartlation is for people aged 18 and over.
