Encryption at Rest
Files you store are kept in our cloud storage, which encrypts stored files with AES-256. Connected Google account authorizations and synced voice signatures are also encrypted in our database.

Data Security Measures
Encryption in Transit
KolWrite connects to our servers over encrypted HTTPS/TLS connections.
Where it is hosted
Our main servers are in Germany, and the GPU computers we operate ourselves are in Israel. Our cloud infrastructure providers store files and deliver our websites from global networks. Cloud GPU servers may be in different countries, and cloud AI requests may be routed to any region with capacity.
Security limits
No system is perfectly secure, and we cannot guarantee that information will never be compromised.
User Control and Data Privacy
AI and training
We do not use your content to train AI models. Before a cloud AI feature sends your content to the provider that runs the model, the app asks for your consent; features that run on your device, such as on-device transcription, do not send your content to these providers.
Deletion and retention
You can delete your recordings, files, chats and account at any time. Your content stays until you delete it. Records of AI requests on our servers are deleted 30 days after each request, or sooner if you delete the chat. Deleted data may remain in backup copies until those copies are replaced or deleted.
