Protecting your data is important to us. The DAYF app and the associated website operate entirely offline. No personal data is processed on servers or by third parties.
No account details: No bank connection is required.
No registration: You do not need to create an account.
No cloud storage: All entries remain exclusively on your device.
No cookies, no tracking: The website does not use cookies and does not store personal data.
The values you enter into the app (e.g., income, expenses, fixed costs) are stored only locally on your device and can be deleted by you at any time.
The app is solely intended to display your budget data offline and locally. Data is not shared with third parties and not used for any other purposes.
Since no personal data is processed, no legal basis under the GDPR is required. If you voluntarily enter data (e.g., income, fixed costs), this data will be stored exclusively on your device.
All data remains only on your device. No transfer to us or third parties takes place. You may delete your data at any time directly in the app.
Even though no data is processed by us, you still have the following rights under the GDPR:
Right of access (Art. 15 GDPR)
Right to rectification (Art. 16 GDPR)
Right to erasure (Art. 17 GDPR)
Right to restriction of processing (Art. 18 GDPR)
Right to object (Art. 21 GDPR)
Right to lodge a complaint with a data protection authority
Since no data is stored by us, these rights only apply to the data stored locally on your device.
The app operates fully offline. No data is transmitted over the Internet.
