# Privacy Policy for Tone Check: Message Helper
**Last updated:** 3 November 2026
This policy explains how Tone Check: Message Helper ("Tone Check", "the app", "we") handles your information. The app is published by Theo ("we", "us"). If you have any questions, contact us at stonblazz1@gmail.com
## The short version
- There's no account and no sign-in.
- The message you paste is sent to an AI service only so it can generate your tone check and rewrites. We don't store it on any server.
- Your check history stays on your phone. You can delete it at any time.
- We don't use advertising, ad tracking or analytics.
- If you subscribe to Tone Check Plus, Google Play handles your payment. Our subscription provider, RevenueCat, keeps an anonymous record of your subscription so the app can unlock Plus.
## 1. Information you enter
**The message text, and who it's to (if you choose a recipient).** When you tap "Check my message", this text is sent over an encrypted connection (HTTPS) to our AI processing service. The service passes it to an AI model provider, which generates:
- a short description of how the message might come across
- a tone label
- three suggested rewrites
The text is processed only to produce that result and is sent back to your phone. We don't store your messages on our servers, and we don't use them for advertising or to build a profile of you. Our AI service providers process the text on our behalf, under their own terms, and only to return the result.
Please don't include passwords, bank details or other highly sensitive information in messages you check.
## 2. Information stored on your device
The app keeps the following on your phone only:
- **Check history:** your original messages, the results and the dates.
- **Daily usage count:** used to apply the free limit of 3 checks a day.
This data isn't uploaded to us. You can delete individual checks in History, or delete everything in Settings → Clear history. Uninstalling the app also removes it.
## 3. Purchases and subscriptions
Tone Check Plus is sold as a subscription through Google Play. Google processes your payment under the Google Privacy Policy, and we never see your card details.
We use **RevenueCat** (revenuecat.com) to manage subscriptions. To check whether you have Plus, RevenueCat receives:
- an anonymous app user ID that the app creates
- your Google Play purchase information, such as the product, purchase token, dates and status
- basic device and app details, such as the app version, operating system version, country/store region and IP address, which are used for fraud prevention and delivering the service
This data isn't linked to your name or email by us. RevenueCat's privacy policy is at https://www.revenuecat.com/privacy.
## 4. What we don't do
- We don't sell your personal information.
- We don't share your information for advertising.
- We don't use third-party analytics, ad networks or tracking.
- We don't access your contacts, your location, your photos or your other apps.
## 5. Legal basis (UK/EEA users)
- **Sending your message to the AI:** necessary to provide the service you asked for (contract).
- **Managing subscriptions:** necessary to provide the purchase (contract) and for our legitimate interest in preventing fraud.
## 6. Data retention
- Message text is processed only for the time needed to generate your result, and we don't keep it.
- On-device history stays until you delete it or uninstall the app.
- Subscription records are kept by RevenueCat and Google for as long as needed to provide the subscription and to meet legal, tax and accounting obligations.
## 7. Your rights
Depending on where you live (for example under UK GDPR or EU GDPR), you may have the right to access, correct, delete or restrict the use of your personal data, and to complain to a data protection authority. In the UK, that's the Information Commissioner's Office (ico.org.uk). Because we don't hold your messages or an account, most of your data is under your control on your device. For subscription-related requests, contact us at [CONTACT EMAIL].
## 8. Children
Tone Check isn't directed at children under 13, and we don't knowingly collect personal information from them.
## 9. Security
All data sent from the app uses encrypted connections (HTTPS). No method of transmission or storage is 100% secure, but we take reasonable steps to protect your information.
## 10. Changes to this policy
We may update this policy from time to time. We'll post the new version at this address and change the "Last updated" date.
