Privacy and safety
Quick answer
The token language runs on your computer and what you write is not uploaded. Typo never acts in password fields, payment pages, terminals or code editors. Safe mode keeps every original it changes encrypted on your computer for 30 days, and the log never contains your text. The Platform Lab on this site runs in your browser only.
Runs on your computer
Typo's spelling engine and the token language both run locally. There is no AI model behind them and no server that reads your text.
Where Typo never acts
- Password and PIN fields, and card, bank and identity numbers.
- Sign-in and payment pages, and password managers.
- Terminals and code editors.
- Apps and fields you block yourself.
What is never changed
Code blocks, inline code, links, e-mail addresses, file paths, function and variable names, flags, numbers, versions, quoted text and ALL-CAPS names are kept byte for byte. Words like not, never, without, only, must, always and all are never added or removed.
Safe mode
With safe mode on, Typo first saves every original it changes, encrypted on your computer, for 30 days. If the original cannot be saved, your text is not changed. In Settings you can copy any original back or delete them all. Safe mode is off by default.
The log
A plain log shows which rule ran, where, and how many tokens it saved by estimate. It never contains what you wrote.
The Platform Lab and the demo on this site
Both run the token language in your browser with the same rules as the app. What you paste is not sent anywhere and not stored. The page itself loads like any web page, so your browser and network still see that you visited it.
Still: think before you paste
No tool catches every secret. Do not paste passwords, keys or private customer data into any AI tool you are not allowed to use for that data. The lab warns you when text looks like a password or key, but it cannot catch everything. Read the privacy notice for the details on Typo itself.
