Last updated: 7 July 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 so that we can analyse it, we encrypt what we store, and we never sell your data, nor use it to train AI models.
UnTXT is operated by Sataklela OÜ, a company registered in Estonia, so we act as the data controller for the personal data described here. You can reach us about anything in this policy through our privacy address, and we answer within a few working days.
Most detection signals run as heuristics, while some enhanced signals send your submitted text to our servers for processing. For those signals, we call AI model providers, and at the moment that means OpenAI, Anthropic, and Google. Text excerpts are processed by these providers as subprocessors and are not used to train their models. We call their interfaces with storage and training turned off whenever the provider offers that control.
Saved analyses are encrypted at rest. Each history is sealed with its own AES 256 GCM key, and the app keeps only your 100 most recent entries. Everything travels over HTTPS while it moves to our servers. Data lives in Google Cloud Firestore, which acts as our hosting subprocessor.
You can delete any saved analysis from the history view whenever you like, and the deletion takes effect immediately. Under the GDPR you can also ask for access to your data, correction, portability, or full erasure of your account, and we answer those requests through the same privacy address. Unlike a deletion inside the product, a full erasure request removes your account records entirely, though billing records may be retained where the law requires it.
If this policy changes in a way that matters, we will note the change here and update the date at the top of the page.
