CONFIDENTIALITY AND DATA USE
The app does not process or store user data on its servers.
Images used during stamp recognition processes are not sent or stored on developer servers in any way.
All recognition, analysis and content creation is performed through artificial intelligence services provided directly by OpenAI. The app only temporarily processes the information returned by the analysis on the device.
This approach ensures the highest level of data security.
DISCLAIMER
The Stampify app is for informational purposes only. The stamp values or information displayed should not be considered as investment advice.
The results provided by artificial intelligence do not guarantee 100% accuracy. Users should verify results before making important decisions.
Pricing and Terms

Your subscription will automatically renew at the end of each term and will be charged through your iTunes account. You can turn off auto-renewal in your iTunes account settings. However, there is no refund for the charged portion of the period used.
