Privacy Policy
1. Who We Are
GraviTalk (the “App”) is a mobile application designed to help you practise and improve your public speaking and communication skills. The App is operated by Splash Consulting Partners LLC (“we,” “our,” or “us”), a limited liability company organised in the United States. If you have any questions about this policy, contact us at support@gravitalk.com, or via our contact page.
2. The Short Version
- We collect your email address and the text transcripts your phone creates from your practice sessions.
- Your voice is transcribed right on your own device. The audio recording itself never leaves your phone — only the text does.
- That text is analysed by AI to give you coaching feedback. We do not sell your data to anyone.
- We store your session history — transcripts, scores, and coaching for each session — so you can reopen past sessions and track your progress over time.
- You can request deletion of your account and all your data at any time.
3. What Data We Collect
3a. Account Information
When you register, we collect:
- Email address — used to identify your account and send account-related communications (e.g. password reset). We do not use it for marketing without your explicit consent.
- Password — stored as a secure one-way hash. We never store or see your plain-text password.
3b. Your Practice Sessions (Voice Becomes Text — On Your Device)
When you use GraviTalk to practise:
- Your voice is recorded on your device for the length of your session.
- The recording is transcribed into text on your device, by speech-to-text that runs locally on your phone. Your audio is never uploaded to us, or to anyone else.
- Only the resulting text transcript is sent — securely over HTTPS — to our backend, where AI generates your coaching feedback across three dimensions: Substance, Language, and Delivery.
- The audio recording is discarded on your device once the transcript is produced. Because the audio never leaves your phone, we never receive it, store it, or have any way to access it.
A note on future features. Advanced voice coaching that analyses pace, pauses, and vocal delivery is planned for a future “Pro” release. Those features may require sending an audio recording to a specialised processing service. If we ever build them, we will update this policy and ask for your consent before any feature sends your audio anywhere. Until then, your audio stays on your device.
3c. Session Data
For each practice session we store:
- The text transcript of each session
- Session scores (Substance, Language, Delivery) — retained indefinitely to power your progress tracking
- Session metadata: date, time, duration, mode (Freestyle or Directed), prompt used (if Directed Mode), and filler word counts
- AI-generated coaching feedback for each session
3d. App Usage Data
We may collect basic, non-identifiable app usage information such as app version, device operating system version, and general error/crash logs.
We do not use third-party analytics SDKs (e.g. Firebase Analytics, Mixpanel) at this time. If this changes, this policy will be updated.
4. How We Use Your Data
| Data | Why We Use It |
|---|---|
| Email address | Account login, password reset, critical service communications |
| Text transcript (each session) | Sent to our AI service to generate your coaching feedback, and displayed to you when you view or reopen a session’s analysis |
| Session scores and metadata | To show your progress over time on the dashboard and journey screen |
| AI coaching feedback | Displayed to you as your personalised coaching output |
| Filler word detection data | To identify your personal filler word patterns and show trends |
We do not use your data to train AI models. Your transcripts are processed to generate your feedback and are not retained or shared for model-training purposes.
5. Third Parties Who Receive Your Data
We use a small number of trusted third-party services to operate the app. These services receive only the data necessary to perform their specific function:
| Service | Purpose | Data Shared |
|---|---|---|
| Anthropic | AI text analysis — generates your Substance, Language, and Delivery coaching | Text transcript only — never your audio |
| Railway | Cloud hosting for our backend server and database | Stores your account and session data (text) securely |
We do not sell, rent, or trade your personal data to any third party for marketing or commercial purposes.
6. Your Consent — Recording Notice
Before your first recording, GraviTalk asks for your explicit consent. By accepting, you confirm:
- You are recording only yourself
- You understand that recording other people without their consent may be illegal in your jurisdiction and that you accept responsibility for compliance with applicable laws
- You consent to your recording being processed as described in this policy
You can withdraw consent at any time by deleting your account.
7. Data Storage and Security
- Speech-to-text runs entirely on your device — your audio is never transmitted to us or to any third party.
- All data is stored on Railway’s cloud infrastructure, hosted in secure data centres.
- All data in transit between the app and our servers is encrypted using HTTPS/TLS.
- Passwords are hashed using bcrypt — we cannot recover your password, only reset it.
- Access tokens are short-lived and stored securely on your device.
- We maintain regular database backups to protect against data loss.
- We do not store AI provider API keys on your device — all AI calls are made server-side.
8. How Long We Keep Your Data
| Data Type | Retention |
|---|---|
| Account information (email, password hash) | Until you delete your account |
| Session scores and metadata | Indefinitely (powers your progress tracking) |
| Session transcripts and coaching (per session) | Indefinitely (lets you reopen any session’s full analysis) |
| Audio recordings | Never transmitted to us — created and discarded on your own device |
| Account deletion request | 14-day grace period, then permanent deletion (see Section 8a) |
8a. Account Deletion
Deleting your account. You can delete your account directly in the app (Settings → Delete Account) or from the web — see Section 8b.
When you confirm deletion, your account is scheduled for deletion with a 14-day grace period. During those 14 days you can restore your account simply by logging back in. After 14 days, your account and all associated personal data — transcripts, scores, coaching history, and account information — are permanently and irreversibly deleted.
One anonymized record is retained. To prevent abuse of our one-time free trial, we keep a one-way anonymized record (a cryptographic hash) derived from your email address. This record cannot be reversed to reveal your email, contains no personal information, and is used solely to ensure a free trial is not claimed more than once. It is retained after deletion for this purpose.
Google Play subscriptions. Deleting your account does not automatically cancel a Google Play subscription. During deletion, the app offers to cancel your subscription for you; you may also decline and manage it yourself in Google Play → Subscriptions. If you elect cancellation, your subscription will not renew. Restoring your account within the grace period does not reverse a cancellation. Any remaining paid time is lost when your account is permanently deleted.
8b. Deleting Your Account From the Web
If you cannot access the app, you can request deletion by emailing support@gravitalk.com from the email address registered to your account. Instructions are also available at gravitalk.com/delete-account.html. Web requests are processed within the same 14-day framework described above.
9. Your Rights
You have the right to:
- Access the data we hold about you
- Correct any inaccurate information
- Delete your account and all associated data (see Section 8a for how deletion works)
- Export your session history (we will provide this in a readable format on request)
- Withdraw consent for recording at any time
To exercise any of these rights, contact us at support@gravitalk.com, or via our contact page. We will respond within 30 days.
10. Children’s Privacy
GraviTalk is intended for users aged 18 and over. Our registration flow requires users to confirm they are 18 or older before creating an account. We do not knowingly collect personal data from anyone under 18. If you believe a minor has created an account, please contact us and we will delete it promptly.
11. Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will update the “Last Updated” date at the top of this page, and notify you via the app or by email if the changes are material. In particular, if we ever introduce a feature that sends your audio recording to an external service, we will update this policy and ask for your consent before that feature is enabled. Continued use of GraviTalk after changes are posted constitutes acceptance of the updated policy.
12. Contact Us
If you have any questions, concerns, or requests regarding this Privacy Policy or your personal data, contact us at support@gravitalk.com, or reach us through our contact page.
