Privacy Policy

This Privacy Policy describes how YITONGXI LLC ("PotatoPost", "we"), a Delaware limited liability company, handles personal data for potatopost.tw.

1. Information We Collect

• Account & contact data — e.g. your email address when you join the waitlist or create an account.
• Brand & content data — the brand materials and content descriptions you provide and the content you generate, to provide the Service.
• Billing data — handled by our payment processor, Stripe; we do not store full card numbers.
• Usage & device data — basic analytics and logs to operate and secure the Service.

2. How We Use It

To provide and improve the Service, process payments, communicate with you (including product and launch updates you signed up for), provide support, and meet legal obligations.

3. AI Processing

To generate content we send your content descriptions and relevant brand materials to AI model providers acting as our sub-processors. We do not sell your content.

4. Sharing & Sub-processors

We share data with service providers that help us operate, such as hosting, our database/storage provider, our payment processor (Stripe), and AI model providers — only as needed to provide the Service.

5. Analytics & Cookies

We use Google Analytics 4 to understand how this site is used. It records aggregate usage — pages viewed, the site or search that referred you, browser and device type, and an approximate location derived from your IP address. We do not use it to collect your name, email address, or any other information that identifies you personally, and we do not use it for advertising or to build advertising profiles.

Google Analytics sets cookies in your browser (named _ga and similar) to recognise repeat visits. The data is processed by Google as our service provider under Google’s Privacy Policy.

You can opt out at any time: block or delete cookies in your browser settings, or install Google’s Analytics opt-out browser add-on. Opting out does not affect your ability to use the Service.

6. International Transfers

We operate from the United States and may process data in the U.S. and other countries. Where required, we use appropriate safeguards for cross-border transfers.

7. Data Retention

We keep personal data for as long as needed to provide the Service and meet legal obligations, then delete or anonymize it.

8. Your Rights

Depending on where you live, you may have rights to access, correct, delete, or export your data, and to object to or restrict certain processing. To exercise them, contact us.

9. Marketing Emails

If you join the waitlist or opt in, we will email you product and launch updates. You can unsubscribe at any time using the link in each email.

10. Security

We use reasonable technical and organizational measures to protect your data, including tenant isolation, encryption in transit, and access controls. No method is 100% secure.

11. Children

The Service is not directed to children and is not intended for anyone under the age of majority in their jurisdiction.

12. Changes

We may update this policy and will post the new version here with a revised date.
