Privacy Policy

Last updated: 31 August 2026

This policy covers the private applications available at poseidon4o.com (the “Service”), operated by a private individual for personal and family use. The Service is not a commercial product, has no public sign-up, and is not offered to the general public.

Who can use the Service

Access is limited to the operator and a small number of invited family members. There is no self-registration.

Google user data we access

When you sign in with Google, the Service may request access to the following, strictly on behalf of the signed-in account and only for the features you use:

How we use it

Google user data is used solely to provide the features you invoke — nothing else. It is never used for advertising, profiling, marketing, credit assessment, or training machine-learning or AI models.

Limited Use disclosure

The Service’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Storage and security

All data is processed and stored on infrastructure controlled solely by the operator. OAuth refresh tokens are encrypted at rest and traffic is served over HTTPS. No Google user data is passed to any third-party service.

Sharing

Google user data is never sold, rented, or shared with any third party. It is not transferred to anyone other than the account holder it belongs to, except where required by law.

Retention and deletion

Data is retained only while a feature needs it. You may revoke the Service’s access at any time at myaccount.google.com/permissions, which immediately stops all further access. To request deletion of any data the Service still holds, contact us at the address below and it will be removed.

Changes

If this policy changes, the revised version will be posted on this page with a new “last updated” date.
