This app is maintained by one person. If something is broken, if something is missing, or if you want to argue with one of the coach’s rules, write and that same person answers.

What to say
Four things make almost any problem clear the first time: what you were doing, what you expected to happen, what happened instead, and your app version and phone model. If the problem is visible, a screenshot beats the description.

Frequently asked
Do I need an account?
No. The whole app works with no account: pick a routine, log your sets, and it all stays on your phone. Signing in is optional and only adds backup and carrying on from another device.
What happens to what I already logged if I sign in?
It goes up. Everything you logged with no account — even months of it — is uploaded in one go the first time you sign in, and stays on the phone in the meantime.
And if I sign out?
Signing out clears the training stored on that phone, because one account’s data cannot be left in view of the next. Whatever had already been uploaded stays in your account and comes back down when you sign in again.
Where is my data?
With no account, only on your device. With an account, also on the service’s server, hosted in the European Union. There are no ads, no analytics and no tracking — the privacy policy sets it out in detail.
Are there ads or a subscription?
There are no ads of any kind. Costia Premium is an optional subscription that adds the AI coach — the in-session assistant and routine design by conversation. Logging, the rules that set your loads and everything else are free and work without an account.
How do I cancel Premium?
In the subscription settings of the store account you bought it with. Cancelling stops the next renewal; Premium lasts until the end of the period already paid. It is the same subscription in Costia Finance, so cancelling it once cancels it for both.
What is the family plan?
Premium Family covers up to 4 people, the owner included, in Costia Training and Costia Finance. The owner pays and invites the others from Profile › Your family; members can leave at any time. The AI included each month is shared by the whole family.
How do I log a bodyweight set?
The weight logged is what you add: on unweighted pull-ups or dips leave it at zero and the set shows as “bodyweight”. With a belt, enter the plate and it shows as “bodyweight +10 kg”.
Can I use it on two devices?
Yes, by signing in with the same account on both. Training syncs; what does not travel is the device preferences — theme, language, weight unit and keep-awake — which belong to each device on purpose.
How do I delete my data or my account?
From the deletion page, below. It works whether or not you are signed in.
