Gridlight

Gridlight privacy policy

Gridlight is a game that works on your device. It has no accounts and doesn't ask who you are.

Play records, only if you agree

When you first open the game, it asks whether you want to share anonymous play records. If you say yes, it sends a record of each game you play from then on:

  • what you build and how the game goes: places, plants, lines, money, the power delivered, the choices you make, how the game ends and when it was played;
  • the game's version, your iOS version and your screen size;
  • a random player ID that the game makes on your device. It isn't linked to your name, your Apple ID or anything else about you.

The records don't contain your name, your Apple ID, your location, your contacts, your photos or anything else from your device. Your device's internet address is seen when a record arrives, but it isn't kept with the records.

You can turn this off at any time in Settings. Then nothing more is sent, and records waiting to be sent are deleted. Games you play while it is off are never sent, not even if you turn it on again later.

The records are used to understand how people play and to make the game better balanced. They are seen by the developer, and by service providers who help him store and analyse them. They are kept on a server in Germany and copied to the developer's computer to be analysed, Cloudflare passes them on the way, and they are deleted after 24 months at the latest. They are not sold, and not combined with data from other apps or websites.

To have your records deleted sooner, email felix.kunz@kunzengineering.ch with the player ID shown in Settings.

Everything else stays on your device

  • Your progress, your saved game and your settings are kept on your device only. Deleting the app deletes them.
  • Gridlight doesn't read your contacts, photos, location, camera, microphone or any other data on your device. If you choose Save Image for the picture of your world at night, it adds that one picture to your photos.

The waitlist on this website

If you join the waitlist, we send one email to confirm your address. Once you confirm, your email address is kept with Resend, the service that sends our email. It is used for one thing: an email the day Gridlight is out on the App Store. It isn't shared, sold or used for anything else.

To be taken off the list, write to felix.kunz@kunzengineering.ch and your address is deleted.
