TildeWork LLC (“we”) describes below how the iPhone app “HakoCard” (the “App”) handles users’ information.
The App handles the following information that you enter:
The information you enter is stored only in the Keychain on your device. It is not sent to our servers or to any third party, and we do not collect it. No account is required, and nothing is synchronized to the cloud (such as iCloud).
The App shows no ads, does not analyze your usage, and does not track you across other companies’ apps or websites. No third-party analytics or advertising tools are included.
The App uses Face ID or Touch ID through iOS. The App never obtains or stores your face or fingerprint data.
When you use camera scanning, the App reads the card number, expiry date, cardholder name and security code from the camera image and fills them into the input fields. Reading is done only on your device, using an iOS feature (VisionKit). Images and video are not saved and are not sent to us or to any third party. The camera is used only if you allow it.
Notifications about card expiry are created on your device, and only if you allow them. They do not go through any external server.
When you export a backup, a file encrypted with the password you set is created. You are responsible for keeping the file and the password safe. We cannot see the contents of a backup file and cannot recover the password.
The App hides card information in the app switcher and while the screen is being recorded. It shows a notice when a screenshot is taken.
The App may offer a one-time purchase that removes the limit on the number of cards. Purchasing, payment, and verifying or restoring purchases are handled by Apple’s App Store. We do not receive your payment information (such as card numbers). Whether you have purchased is checked on your device through Apple’s mechanisms, without our servers.
Because we do not obtain the information entered in the App, we do not provide it to third parties.
When you delete a card in the App, its information is removed from your device. When you delete the App, the information it stored is in principle removed as well. Backup files you exported remain where you saved them, so please delete them yourself when they are no longer needed.
We may change this policy as needed. A changed policy takes effect when it is posted on this page.
