Last updated: 2 September 2026 · Applies to untxt.uk and the UnTXT web application. The Chrome extension has an additional policy that covers its specific behaviour.
In one sentence: we process the text you submit in order to analyse it, we encrypt whatever we store, and we never sell your data or use it to train AI models. That is genuinely the whole of it.
UnTXT is operated by Sataklela OÜ, a company registered in Estonia, which makes us the data controller for the personal data described here. Raise anything here with us through our privacy address. We answer within a few working days.
Most detection signals run as heuristics, so they never leave your machine. Some enhanced signals do send your submitted text to our servers for processing, and for those we call AI model providers, which at present means OpenAI, Anthropic and Google. Those providers handle text excerpts as subprocessors, and the excerpts are not used to train their models. Where a provider offers the control, we switch storage and training off.
Saved analyses are encrypted while they sit at rest, always. Each history is sealed under its own AES 256 GCM key, and the app keeps only your 100 most recent entries, so the pile never grows without limit. Everything travels over HTTPS as it moves. The data itself lives in Google Cloud Firestore, which is our hosting subprocessor, rather than on hardware that we own.
Any saved analysis can be deleted from the history view whenever you want, and that deletion takes effect immediately. The GDPR additionally gives you the right to ask for access to your data, for correction, for portability, or for full erasure of the account, and requests of that kind reach us at the same privacy address. Unlike a deletion inside the product, a full erasure request clears your account records entirely. To be clear, billing records may still be retained where the law requires that of us.
Should this policy change in a way that genuinely matters to you, we will note the change here, and the date at the top of the page gets updated to match, so that you can tell at a glance whether anything has moved since you last looked.
