Emoji Memory Jetpack: privacy and terms of use

Emoji Memory Jetpack has no account, no ads and no server of its own, and it saves nothing on the phone. The only data that leaves it is a set of anonymous game statistics.

I, Tiago Danin, am the developer and the controller of this data under the LGPD (Lei 13.709/2018). If you are in the EU, the GDPR gives you the same rights and I answer them the same way. Write to TiagoDanin@outlook.com about any of it.

What the app uses on the phone

The game reads the phone's motion sensor to tilt the cards and move their shine. Those readings stay in memory while the game is open and are never stored or sent.

What the app sends

Google Analytics for Firebase records how the game is played: when a round starts, how long the first flip takes, each pair matched or missed, the number of moves and the time when you win, when you restart, pause or leave a round, and when you open the About window and which link you tap there. Like any app using the SDK, it also records automatic events such as the first open and each session, together with an ID for this installation, the device model, Android version, app version and approximate location. The SDK may read the install referrer (how you got to the game on Google Play). The game turns off the advertising ID, so the SDK neither reads nor sends it. The game does not send a user ID, because it has none, and does not use this data for advertising.

For this, the game now uses the internet connection. The source code is public on GitHub, at TiagoDanin/Emoji-Memory-Jetpack, so anyone can check what is sent.

Who else receives it

Google, which runs Firebase and processes this data on my behalf, on servers that may be outside Brazil, including in the United States. Their terms: Firebase privacy and Google Privacy Policy.

I do not sell this data, share it with advertisers, or hand it to a data broker. The statistics are used to find bugs and to tune the game, on the basis of my legitimate interest in keeping it working.

The About window links to this page, to the terms of use and to the source code. They open in your browser, which follows its own privacy policy.

How long it is kept

Statistics are kept for the retention period configured in Firebase, after which Google deletes them.

Your rights

Since the statistics carry no name or account, I usually cannot tell which ones are yours. You can still ask me what exists, ask me to delete it, or object to it, at TiagoDanin@outlook.com. You may also complain to the ANPD, Brazil's data protection authority.

Children

The game is not directed at children. I do not knowingly collect data from children under 13. If you believe a child's data reached me, write to me and I delete what I can find.

Changes

If this policy changes, the date at the top changes with it. A change in what is collected is described here before the version that makes it is published.

These terms apply to anyone who uses Emoji Memory Jetpack. Using the app means you accept them.

Who provides the app

Tiago Danin, a private individual in Brazil. "I" and "me" below mean him.

What it is

A small memory game: flip the cards and find the matching emoji pairs. It is free, with no ads and no purchases.

The code

The source is public on GitHub, at TiagoDanin/Emoji-Memory-Jetpack, under the MIT licence. That licence governs what you may do with the code, including copying and modifying it.

Liability

The app is provided as it is, with no warranty, as the MIT licence also says. To the extent Brazilian law allows, I am not liable for damage caused by using it. Nothing here removes a right that the law gives you and that a contract cannot take away, such as those in the Código de Defesa do Consumidor.

Changes

If these terms change, the date at the top changes with them.

Law

Brazilian law governs these terms. Anything an email cannot settle goes to the courts of Belém, Pará, without prejudice to your right as a consumer to sue where you live.
