Certo, published by Black Hart Consulting LLC · Last updated July 2026
In short: Certo collects no personal data, has no account system, and stores your study progress only on your device.
Certo has no sign-up or account. We do not collect your name, email, contacts, location, or any personally identifiable information, and we use no third-party analytics, advertising, or tracking SDKs.
Your study progress, flashcards, notes, streaks, and settings are stored locally on your device using Apple's on-device storage. This data is never transmitted to us. Deleting the app removes it.
The app may download updated question banks from our content server (blackhartconsulting.com) so material stays current. These requests are anonymous, contain no personal data, and transfer only the study content itself.
In-app purchases are processed by Apple through the App Store. We never receive or store your payment information; Apple's privacy policy governs payment data.
Certo is rated 4+ and knowingly collects no information from children. Because we collect no personal data, none is gathered from users of any age.
We hold no personal data about you on our servers, so there is nothing for us to access, correct, or delete on our side. On-device data is fully under your control.
We may update this policy; the date above reflects the latest version.
Certo is independent study material and is not affiliated with, authorized, or endorsed by any certification body. Exam names and codes are trademarks of their respective owners, used nominatively. Contact: hello@blackhartconsulting.com
