TennisTrend uses the built-in database on your iOS device. This means that the data you enter and that which is recorded by the app remains at all times on your iOS device. It is not transmitted anywhere else. This has the advantage of privacy.

The only way to transfer data from the device is by taking a screen shot of the app pages. These can for instance then be printed from the Photos app or sent elsewhere by the Mail app, and transferred during a backup of the iOS device to a computer.

The database is preserved during updating of the app on the iOS device.

This privacy advantage is, however, a data safety vulnerability, in case you lose or irreparably damage your iOS device and any backups on your computer. It is therefore suggested that you take screen shots of important matches you may wish to look back on, and back these photos up to a computer for safer keeping.
