We share some of your personal information, which may include device identifiers and behavior data, with our partner, Google Analytics, to help us analyze and improve our services. For more details, please see Google's Privacy Policy.

Data Security

We implement strong security measures (including, but not limited to, using industry-leading encryption algorithms and a database key rotation policy) to protect your personal information from unauthorized access, alteration, disclosure, or destruction.

Your Rights

Regardless of any penalties applied to your account, you always have the right to:

  • Access the personal information we hold about you
  • Request correction of your personal information
  • Request deletion of your personal information

Data Storage

Text data submitted by users is stored on our Tencent Cloud servers located in Hong Kong. User-uploaded files are stored on Cloudflare and Yumio's object storage services, depending on the user's selected file storage pool.

Data Deletion

Except when a user requests it, we have the right to delete data submitted and uploaded by users to reclaim available resources, based on maintenance needs.

Before we proactively delete user data, we should notify the user and provide an opportunity for backup.

Data Export

Users can export their personal information by contacting us at lily@solsynth.dev.

NOTICE: Once the data export was done, we will delete the exported data in our database immediately. Which means you no longer have access to your Solarpass account. We use the email address we recieved the export request to validate your identity. And that's the final step in the process. We won't send any further confirmation emails.
