Chain LettersPrivacy policy
Effective
Chain Letters is a word game. It needs no account, and we don't collect your personal data. In short:
- The app saves a few things on your device: your language, whether sound is on, and your best score in each language.
- The words you play are checked on your device and never leave it.
- On Android, the app shows ads from Google AdMob. To serve them, Google collects some information from your device, such as its IP address and advertising ID. Where the law requires it, the app asks for your consent first.
- The app connects to the internet only for these ads.
Who we are
Chain Letters is made by José Gutiérrez de la Concha (Spain), who publishes it as Not Only Bits. “We” in this policy means Not Only Bits. For any question about this policy or your privacy, write to hello@notonlybits.com.
What stays on your device
The app saves your language, your sound setting and your best score in each language in its own storage on your device, so that it remembers them next time. It never sends them to us or to anyone else. Uninstalling the app, or clearing its data, removes them. If your phone backs up its apps, Android may include them in your Google backup.
The words you trace are checked on your device against the word lists that come with the app, and aren't sent anywhere. Only your best scores are saved, not the scores of your other games.
Advertising
On Android, Chain Letters shows a banner on its title screen and, after some games, a full-screen ad. Google AdMob, Google's advertising service, chooses and serves these ads. We don't receive any information that identifies you.
According to Google, its ads software collects:
- your device's IP address, which can give its approximate location;
- how you interact with the app and its ads, such as app launches, taps and video views;
- diagnostic information, such as how the app and the ads software perform;
- your device's advertising ID and app set ID.
Google uses this information to show and measure ads, to prevent fraud and, if you allow it, to personalize the ads you see. It is encrypted on its way to Google. How Google uses information from apps that use its services explains more.
Your consent. Where the law requires it, for example in the European Economic Area and the United Kingdom, the app shows Google's consent form before requesting any ad. There you can choose whether Google may use your information for personalized ads. To change your choice later, tap Privacy choices, which the app's title screen shows wherever the consent form applies.
Other controls. You can reset or delete your advertising ID in your phone's settings, and turn off ad personalization in Google's ad settings. Without personalization, you still see ads, chosen from what you're doing in the app rather than from a profile.
Children
Chain Letters is not directed at children under 13, and we don't knowingly collect information from them.
Your rights
Depending on where you live, you may have the right to access, correct or delete your personal data, to object to its use, and to complain to your data protection authority. We don't hold personal data about you. The information collected for ads is held by Google, which handles requests about it; your consent choices and the controls above also apply. If you need help, write to hello@notonlybits.com.
Changes to this policy
If the app starts collecting anything new, for example to save scores online or to report crashes, we will update this policy before that version is released and change the date at the top.
