Security statement
✓
No content database
No SQL, NoSQL, or file store for translated content. No schema, no tables, no records.
✓
No persistent logs
RAM-only ring buffer, max 40 entries. Restart wipes everything. No log files to hand over.
✓
No training on your text
LibreTranslate runs static pre-trained models. Your input is never used to update or fine-tune any model.
✓
No third-party APIs (default)
In LibreTranslate mode, zero external API calls are made. The entire stack runs on-premises.
✓
Open-source engine
LibreTranslate is fully open-source (AGPLv3). You can verify exactly what runs on the server.
✓
History stays on your device
Translation history lives exclusively in your browser's localStorage — never synced to us.

About this tool

I build tools with one goal in mind: give people maximum privacy, maximum control, and zero friction. No accounts. No subscriptions. No data harvesting. Just tools that do what they say and nothing more.

HyperTranslate runs entirely on my own server in Europe. Your text never touches Google, AWS, or any third-party cloud — unless you explicitly choose the Google Translate engine, which is clearly labelled as external before use. The default LibreTranslate engine is open-source, runs 100% locally, and processes everything in RAM. Nothing is stored. There is no database. There is no log of what you translated.

75–85% of the code in this tool was written by Claude AI (Anthropic). I directed the architecture, made decisions about privacy and security, adapted the implementation, and built the infrastructure it runs on. I believe in being transparent about how these tools are made.
