Chitchart ("the app", "we") turns a chat you export from a messaging app into statistics and shareable cards. The app is built so that your messages never leave your device. This policy explains what the app handles, where it stays, and the few cases in which data is sent anywhere.
## The short version
- Your chats are read and analyzed **only on your device**. We have no servers that receive them.
- There is **no account** and **no sign-up**.
- We do **not** use analytics, advertising or tracking SDKs, and we do not show ads.
- The only data that leaves your device is what is needed to process an in-app purchase (see "Purchases" below).
## How to delete your data
This section explains how to delete data related to the Chitchart app (developer: Selçuk Korkusuz).
**1. Chats and statistics on your device**
- Delete one chat: on the home screen, swipe the chat to the left and tap **Delete**.
- Delete everything: open **Settings** and tap **Delete all saved chats**.
- Or uninstall the app.
Deletion is immediate and permanent. This data exists only on your device, so no copy is kept anywhere else.
**2. Purchase data held by our purchase provider (RevenueCat)**
1. Email **mazellangames@gmail.com** with the subject **"Chitchart – delete my data"**.
2. Include the order number from your Google Play or App Store receipt (for example `GPA.1234-5678-9012-34567`) so we can find your record. We have no other way to identify you, because the app has no accounts.
3. We delete the record within **30 days** and confirm by email.
**What is deleted:** your anonymous purchase ID, your purchase and subscription history, and the related technical data (device model, operating system and app version, country) stored by RevenueCat.
**What is kept:** Google Play and Apple keep their own records of your transactions under their own policies; we do not control these. Your Pro purchase stays linked to your store account, so you can still restore it later. We keep your request email only until the request is completed.
## Chats you import
When you share or pick a chat export (a `.txt` or `.zip` file), the app reads it on your device to calculate statistics: message counts, reply times, active hours, most-used words and emojis, and similar figures.
- **Messages are not stored.** The original file is processed in memory. Any copy of it that the app receives from the share sheet or file picker is deleted after it has been read.
- **What is kept on your device:** the calculated statistics for each chat. These include the participants' display names as they appear in the export, counts, most-used words and emojis, the date and text of the chat's first message (shown on one of the cards), and a small random selection of short messages from each participant (at most 250 per person, each under 140 characters) used by the "Who said it?" game. They are stored in the app's private storage on your device so you can open the chat again later.
- **Deleting it:** you can delete a single chat by swiping it on the home screen, delete everything in Settings, or uninstall the app. Deleted data cannot be recovered, because no copy exists anywhere else.
The sample chat in the app is made up and contains no real people.
## On-device AI summary (iPhone only)
On supported iPhones, the app can write a short summary of a chat using Apple's on-device language model (Apple Intelligence). The model runs entirely on your device. Neither the messages nor the summary are sent to us or to Apple by the app. The summary is stored on your device together with the chat's statistics and is deleted with it.
## Cards you share or save
Cards are created on your device. A card is shared only when you choose to share it, and only with the app or person you select (for example Instagram, a messaging app, or AirDrop). From then on, that service's own privacy policy applies. You can hide names on cards before sharing.
When you save a card or video to your photo library, the app asks for permission to **add** photos. It does not read your existing photos or videos.
## Purchases
Chitchart Pro is sold through Apple's App Store and Google Play. Payments are processed entirely by Apple or Google; we never see your payment details.
To validate purchases and restore them across reinstalls, the app uses **RevenueCat**, a purchase management service. RevenueCat receives:
- a random, anonymous app user ID generated by RevenueCat (not linked to your name, email or chats),
- purchase and subscription details from the store (product, price, dates, transaction IDs),
- basic technical data such as device model, operating system version, app version, country or region, and IP address.
RevenueCat processes this data on our behalf only to provide purchase services. **No chat content, statistics or names are ever sent to RevenueCat.** RevenueCat's privacy policy: https://www.revenuecat.com/privacy
## Data we collect
Apart from the purchase data described above, which is held by RevenueCat and the app stores, we do not collect, receive or store any personal data. We do not sell or share personal data, and we do not use it for advertising or tracking.
## Permissions
- **Photos (add only):** to save cards and videos to your photo library when you ask the app to.
- **Internet:** used only to communicate with the app stores and RevenueCat for purchases.
## Children
Chitchart is not directed to children under 13, and we do not knowingly collect personal data from children.
## Your rights
Because your chats and statistics exist only on your device, you remain in full control of them and can delete them at any time as described above.
For purchase data, you can contact us to request access to it, or delete it as described in "How to delete your data" above. Depending on where you live, you may have rights under laws such as the GDPR (EU/UK) or KVKK (Türkiye), including the right to access, correct, delete or object to the processing of your personal data, and the right to complain to a data protection authority.
## Changes to this policy
If we change how the app handles data, we will update this page and change the effective date above. Significant changes will also be noted in the app's release notes.
