• Process subscription payments and manage your account tier (free or premium).
• Detect, prevent, and address technical issues, fraud, or abuse.

We process your data on the legal bases of contract performance (to deliver the Service you signed up for), legitimate interest (to improve the Service), and consent (where applicable, such as marketing communications).

3. Data Storage and Security

Your data is stored and processed using Supabase, a cloud-hosted platform that provides database, authentication, and file storage services. Supabase infrastructure is hosted on Amazon Web Services (AWS) in secure data centers.

We implement the following security measures:

• All data transmitted between your device and our servers is encrypted using TLS (Transport Layer Security).
• Database access is protected by Row-Level Security (RLS) policies, ensuring users can only access their own data.
• Authentication tokens are securely managed and expire after a defined period.
• Passwords are hashed using industry-standard algorithms and are never stored in plain text.
• Some learning data is cached locally on your device using encrypted local storage (Drift and Hive) for offline access.

While we take reasonable measures to protect your information, no method of electronic transmission or storage is 100% secure. We cannot guarantee absolute security of your data.

4. Third-Party Services

We use the following third-party services that may process your data in accordance with their own privacy policies:

We do not sell, rent, or trade your personal information to third parties for marketing purposes.

• Service Providers: With the third-party providers described in Section 4, strictly to operate the Service.

Aggregated, anonymized data that cannot identify you may be retained indefinitely for analytics and service improvement purposes.

8. Cookies and Tracking Technologies

Our website (seottak.com) may use essential cookies to ensure proper functionality, such as session management. We do not use third-party advertising or tracking cookies.

The seottak mobile application does not use cookies. Local data storage on your device (for offline learning progress) is managed through the app's internal database and is not shared with third parties.

9. International Data Transfers

ERLIVION GLOBAL LLC is based in the United States. If you access the Service from outside the United States, your information may be transferred to, stored, and processed in the United States or other countries where our service providers maintain facilities.
