Privacy Policy — Translate Slides with AI

Translate Slides with AI has no servers, accounts, ads, analytics, or tracking, and never sells or shares data. The developer never receives your text, your settings, or your API keys. The only personal data the add-on touches is your email address, used solely to verify a Premium subscription (see "Premium payments" below).

• It works only on the presentation you have open. The add-on uses the "current presentation only" permission (presentations.currentonly). It cannot access, list, or read any of your other Google Slides, Drive files, Gmail, contacts, or calendar.
• What happens to your text. When you click Translate (or use the Adapt tab), the text of the open presentation — or only the slide/selection you chose, plus speaker notes if ticked — is sent to the translation engine you selected, and the result is written back into that same presentation:
  • Google Translate (default, built in): translation is performed by Google's own translation service (the Google Workspace LanguageApp service). No third-party request is made.
  • Your own AI engine (optional): if you pick an AI engine (OpenAI GPT, Anthropic Claude, Google Gemini, DeepL, Mistral AI, Meta Llama, DeepSeek, or OpenRouter) and save your own API key for it, the text — along with your optional prompt/instructions, if you set any — is sent to that provider's API using your key. As part of the same run, the add-on may also send up to 8 short source/translation snippets back to the same provider for the optional quality self-check. This all happens under your own account with that provider — review the provider's terms before translating confidential content. The developer is not a party to any of it.
• Your settings and API keys (selected engine, per-engine API keys, your optional prompt, theme choice, and the model id that last worked for each engine) are stored solely in your own Google account (Apps Script user properties). Keys are used only to call the engine you chose; the add-on only ever shows the last 4 characters of a key back to you. Nothing is sent to the developer or anyone else.
• Nothing is retained. The add-on does not save your slides, your text, or any copy of your content anywhere outside the presentation itself.
• Third parties. The add-on operates no external server. Apart from the Premium payment verification described below, the only third-party transmission is the one you configure yourself: your selected AI/DeepL provider, under your own key, only when you choose such an engine. With the built-in Google Translate engine, no slide text goes to any third party.

Premium payments (Paddle)

Premium subscriptions are sold and processed by Paddle — our Merchant of Record — on Paddle's own secure checkout pages. The add-on never sees or stores your card details; Paddle also issues your receipts and handles applicable VAT/sales tax. If you start a Premium purchase or click "Activate Premium", the add-on sends your email address (your Google account email, or the checkout email you type) to Paddle, using a read-only API key, solely to confirm that an active subscription exists. The confirmation result ("premium: yes/no") is stored in your own Google account properties. Nothing else is shared with Paddle, and no payment data ever reaches the developer. Paddle's own privacy policy applies to the checkout.

Permissions used, solely to provide the feature

• See, edit, and configure the current presentation only (presentations.currentonly) — to read the slide text and write the translation back into the open deck.
• Display and run third-party web content in prompts and sidebars (script.container.ui) — to show the translator sidebar.
• Connect to an external service (script.external_request) — used when you choose an AI or DeepL engine, to call the API you configured with your own key, and — if you start a Premium purchase or activation — to verify your subscription status with Paddle (read-only). The built-in engine itself makes no external requests.
• See your primary Google Account email address (userinfo.email) — used only to recognise your Premium subscription (and to pre-fill the checkout email). Never used for marketing and never shared with anyone except Paddle for the verification above.
