CommSensei is a communication-skills practice app. This policy explains what data the app handles and where it goes. The short version: no sign-up is required, we don't run ads, we don't sell your data, and you can delete everything we store about you at any time from inside the app.
When you chat with the AI coach or play the Car Negotiator game, the messages you type are sent over an encrypted connection to our server, which forwards them to Google's Gemini API to generate a response. Google processes this content under its own Gemini API terms. Our server does not save your messages — it only passes them along and returns the reply. Please don't type sensitive personal information (passwords, financial details, etc.) into the chat.
During the current testing phase, chat processing runs on Google's free Gemini API tier. Under Google's terms, content sent to that tier may be retained and used by Google to improve its products and machine-learning models, and may be reviewed by human reviewers. Treat anything you type in the chat as something Google may process for those purposes.
When you first open the app, it creates an anonymous account for you — a random ID with no email, phone number, or password attached. We don't know who you are. This ID lets the app back up your progress and store your onboarding answers. Account data is stored with Supabase, our database provider, and is encrypted in transit.
This data is kept while your account exists and is deleted when you delete it (see below).
To find and fix bugs, the app uses Sentry, a crash-reporting service. If the app crashes or hits an error, Sentry collects a diagnostic report — the error details plus basic device and app information such as device model, operating-system version, and app version. These reports do not include your name, email, or the content of your chats. Sentry processes this data on our behalf to help us keep the app stable.
Open the Progress tab and tap "Delete my data". This permanently removes your account and everything stored with it — onboarding answers, progress backup, and usage events — from our systems. You can also email us at commskill.app@gmail.com and we'll handle the deletion for you.
When you have the coach read a message aloud, the text of that message (coaching lines the app generates, not information about you) is sent over an encrypted connection to Deepgram, our voice provider, which returns the spoken audio. If your device is offline, the app falls back to your phone's built-in text-to-speech instead.
When you use voice input — tapping the microphone to talk to the coach instead of typing — the app records your voice only while you are actively recording, and sends that audio to Deepgram to turn it into text. The recording is used only to produce that transcript and is not stored by us. The microphone is never accessed unless you tap it. As with the chat, please don't speak sensitive personal information (passwords, financial details, etc.).
CommSensei is not directed at children under 13. The personal information the app can hold is limited to the onboarding answers, an optional display name, and an optional age range described above — all of which can be deleted at any time from inside the app.
If this policy changes, the updated version will be posted at this same address with a new "last updated" date.
