Privacy, offline use, and what Vent is — and isn’t.
Vent is a voice-first diary app for iOS and Android with on-device transcription, an encrypted vault, and optional on-device reflection and coaching-style Conversations. It is designed for private spoken reflection, not cloud chat.
Diary and conversation content are not uploaded to Vent. Network use is mainly for the one-time Personal AI download.
Vent’s on-phone speech and reflection models (On-device speech pack and reflection model, downloaded once on Wi‑Fi.) — not a remote chat service. Vents and Conversations are not sent to Vent for processing.
ChatGPT is a general cloud assistant. Vent keeps diary content on your phone, deletes raw audio after transcription, and uses on-device models for reflection grounded in your own entries.
~3.4 GB one-time on Wi‑Fi for the speech and reflection models, separate from your diary vault (which grows with your entries). The app shows the exact size for your build before download.
Yes, after setup. Recording, transcription, and on-device chat do not require internet.
