Privacy
Teltu is made by Andaca LLC, which runs the app and this site and is responsible for this policy.
The app
Teltu has no accounts, no advertising, no analytics and no tracking. The cards you keep stay on your device. The maps are pictures inside the app, so looking at one tells no one where you looked. Subscriptions and donations in the app are handled by Apple, and we never see your payment details.
This site
This site sets no cookies and runs no analytics. It runs a small amount of its own code, so you can move around the map and turn the card on the home page, and it loads nothing from anywhere else. Its host, Cloudflare, sees your IP address in order to deliver the page, as every web host does.
The launch list
If you leave your email at the foot of any page, we keep the address and the date you left it, nothing else. It is stored with Cloudflare, which hosts this site, and is never given to a mailing service. We send one message, on the day Teltu opens, and then delete the whole list.
Donations on this site
Donations on this site are not open yet. When they open, this page will name who handles the payment before any money is taken.
When you write to us
If you write to us, answer one of the open questions on a card, or ask for scholar access, we use what you send only to reply, to check the answer, and to give you access. We do not sell it or share it. Your name goes on a card only if you say yes.
Changes
If any of this changes, this page changes first, with the date.
