Your Data
Stays
Yours.

OiPer is built on a simple premise: your recordings belong to you. Everything runs locally by default. No subscriptions, no accounts, no telemetry.

Local Transcription

All speech-to-text runs on your machine using local AI models. No exceptions.

On-Device Storage

Activity logs, audio files, and transcription history never leave your device.

Optional Cloud

Online text cleanup requires explicit opt-in and your own API key. You stay in control.

Zero Telemetry

We collect nothing. No usage patterns, no analytics sent without your explicit permission.

Start Talking.
Stop Typing.
