Short answers, and a real address at the bottom.

A question looks wrong

Please tell us. Every question in Decadia was checked against a cited source before it shipped, but a bank this size can still carry a mistake, and a wrong answer is the fastest way to lose your trust. Mail [email protected] with the date you played and roughly what the question asked — we will check it against its source and correct it in the next update.

My streak disappeared

Streaks are stored on your device, so they do not follow you to a new phone and they do not survive deleting the app. A streak counts consecutive days on which you finished the Daily Rewind, measured in UTC so everyone changes day at the same moment worldwide.

I bought Premium and it is not showing

Open Decadia Premium and choose Restore Purchases. That asks Apple directly, and works on any device signed in to the Apple Account that made the purchase.

Cancelling a subscription

The annual plan renews until you cancel; the lifetime unlock is a single payment with nothing to cancel. To cancel, open Settings on your iPhone, tap your name, then Subscriptions. Cancelling leaves you with everything that is free forever — the Daily Rewind, your streak, the share card and leaderboards.

Reporting an ad

If an ad was inappropriate, tell us which day you saw it at [email protected] and we will report it to the ad network. Premium removes ads entirely.

Everything else
