Privacy
Last updated: 8 May 2026
The short version: the free tier of sen-say runs entirely on your device. Nothing you type, paste, screenshot, or record leaves your phone. Plus and Premium tiers send selected requests to LLM providers (Anthropic, Groq) to draft replies and analyze tone — that content is processed and discarded; we never store it.
Who we are
sen-say (the "App") is operated by the team behind sensay.me. Reach us at hi@sensay.me.
What we collect, and why
The data the App may collect, depending on which tier you use:
| Data | Collected on | Why | Stored? |
|---|---|---|---|
| Email address | All tiers (account creation) | Authentication, account recovery | Yes, by Firebase Authentication |
| Messages and chat content you paste / type | Plus + Premium only | Sent to the LLM provider to draft replies, decode subtext, analyze tone | No — sent in real-time to the provider, not stored by us |
| Crash and diagnostics logs | All tiers | Detect bugs and stability issues | Yes, via Firebase Crashlytics; no message content included |
| Device identifier | All tiers | Rate limiting and basic fraud prevention | Yes, in our cost-log database, not linked to your identity |
| Subscription status | Plus + Premium only | Entitle premium features | Yes, via RevenueCat (linked to your account) |
Free tier: on-device by design
On the free tier, all language processing happens on your device. The App ships with a compact open-weights language model that runs locally. We chose this architecture deliberately: privacy is the product, not a feature toggle.
Practically, this means: nothing you type, paste, or screenshot in the free tier is transmitted to our servers or to any third-party LLM provider. Free-tier requests do not leave your phone.
Plus and Premium tiers: cloud passthrough, never stored
Plus and Premium unlock more capable cloud models for higher-quality analysis. When you invoke a feature on these tiers, we route your request to the appropriate provider:
- Anthropic (Claude models) for reply drafting and conversation analysis
- Groq (Llama and Whisper models) for translation and audio transcription
We pass your request to the provider, receive the response, and return it to you. We do not store the request content. We do not log the request content. We do not train any model on your content. What we do log: the timestamp, provider, operation, token counts, and latency — never the message body.
What our providers do
Anthropic and Groq each have their own privacy policies. Per their commercial terms with us:
- Anthropic does not train on API data by default.
- Groq does not train on API data by default.
- Both providers retain request/response data only as long as needed to operate the API.
We rely on these commitments. Read their policies at anthropic.com/legal/privacy and groq.com/privacy-policy.
What we never do
- We never sell your data.
- We never use your message content to train models.
- We never share your data with advertisers.
- We never read your messages outside the scope of the request you make.
- We never retain message bodies in our logs.
Where data is processed
Free-tier processing: on your device. Plus + Premium processing: at our LLM providers' infrastructure (United States). Account and subscription data: Firebase + RevenueCat (United States, with EU data residency available where required).
Children
sen-say is not directed at children under 13. The minimum age to use the App is 13 in the United States and 16 in the European Economic Area. We do not knowingly collect data from users below those ages.
Your rights
Depending on your jurisdiction, you may have the right to access, correct, port, or delete the data we hold about you. To exercise any of these rights, email hi@sensay.me from the email address associated with your account. We respond within 30 days.
You can delete your account at any time from Settings → Account → Delete account in the App. Deletion removes your account record from Firebase and RevenueCat. Cost-log entries that contain only timestamps, tokens, and a hashed device identifier are retained for accounting purposes; they cannot be linked back to you after account deletion.
Security
Connections between the App and our servers use HTTPS. Account credentials are hashed by Firebase. Provider API keys never leave our backend. We do not run our own LLM infrastructure — that's a deliberate choice, since LLM providers operate at a security scale we cannot match.
No security model is perfect. If you discover a security issue, please report it to hi@sensay.me.
Changes to this policy
We will update this page when our practices change. Material changes are announced in the App at least 14 days before they take effect. The "Last updated" date at the top of this page reflects the most recent change.
