Your information

You control your records.

Choose the service you use so your request reaches the right place.

The rebuilt Effikos website

Open your account to export workbooks, delete individual workbooks or delete your personal account. Account deletion removes associated personal credentials, sessions and saved workbooks from the active database.

Export anything you want to keep before deletion. See Privacy for the separate treatment of backups and security records.

The previous Effiko mobile app

Email hello@effikos.com from the account email where possible. State that your request concerns the legacy mobile app. We may need to verify ownership before processing it.

Do not send passwords, verification codes or payment-card information. Creating a website account does not transfer or delete a legacy app account.

Calculate and browse without optional tracking. Your choice never changes access to your saved grades.
