Jack Apps/Graphable/Privacy policy
Graphable. Last updated 14 September 2026.
Graphable keeps what you enter on your device. There is no account, no sign-in, no server of ours, no sync and no analytics.
Every function you type, data list you enter, window setting you choose and course workspace you save is written to storage on the device itself, and is read only by the app. None of it is transmitted anywhere. If you delete the app, or lose the device, that work is gone. The free tier keeps nothing at all between sessions.
Purchases, and nothing else. Graphable uses Apple's App Store for payment and RevenueCat, Inc. as its purchase layer. To tell the app whether the unlock is active, RevenueCat receives the transaction and a randomly generated identifier for the installation. It never receives a function, a data list, a plot or a result: the app's purchase code cannot reach them. RevenueCat's own privacy policy is at revenuecat.com/privacy.
Apple's handling of the payment itself is governed by Apple's privacy policy. We never see your payment details.
Nothing. There is no analytics, no advertising, no crash reporter, no tracking, and no profile of you anywhere. We cannot identify you, and we hold no database of users. Nothing is sold or shared, because there is nothing to sell or share.
Graphable is a study tool, and students use it, including students under 13. That changes nothing about what it does. It collects no personal information from anyone of any age, asks for no name, email address or age, contains no advertising, and has no way to contact a user or to let users contact each other. There is accordingly nothing for a parent to request the deletion of, and deleting the app erases everything it holds.
Because your work never leaves your device, you exercise them directly: delete a workspace in the app, or delete the app to erase everything. There is nothing for us to hand over or delete on your behalf. For purchase records held by Apple or RevenueCat, write to the address below and we will pass the request on.
If this policy changes, the date at the top changes with it, and the previous wording is superseded from that date.
