Privacy Policy

Last updated: June 1, 2026

1. Introduction

Seenful (the “Service”) is operated by Haoduo (Hong Kong) Holding Limited (“we,” “us,” or “our”). This Privacy Policy explains how we collect, use, share, and protect information when you use Seenful through our website, mobile applications, and related services.

By using Seenful, you agree to the practices described in this Policy. If you do not agree, please do not use the Service.

2. Information We Collect

We collect the following categories of information:

• Photos and images you import. When you choose to upload or import photos, videos, or other media into Seenful, we receive that content so we can process it and provide the features of the Service.
• Account information. When you join the waitlist or create an account, we collect information such as your email address and, where applicable, account credentials.
• Device and usage data. We may collect device identifiers, operating system, app version, IP address, time zone, language, crash logs, and aggregated usage data (for example, which features you interact with) to help us operate and improve the Service.
• Communications. When you contact us, we keep a record of your messages and our responses.

3. How We Use Your Information

We use the information we collect to:

• Provide and operate Seenful’s core features — including using AI and automated analysis on the photos you import to generate memories, stories, captions, highlights, themes, and other story-driven outputs.
• Personalize your experience and surface content that is relevant to you.
• Improve and develop the Service, including debugging, analytics, and feature research.
• Protect the security and integrity of the Service and detect or prevent fraud, abuse, or violations of our Terms.
• Communicate with you about the Service, including waitlist updates, product announcements, and support.
• Comply with legal obligations.

4. AI Processing of Your Content

A core part of Seenful is the automated, AI-driven understanding of the photos you choose to import. By using the Service you acknowledge that:

• Your photos and related metadata may be processed by automated systems and machine-learning models (including computer-vision and generative models) in order to extract concepts, scenes, moments, people-grouping signals (where supported by your device permissions), and other features needed to produce memories, stories, captions, or recommendations.
• Processing may occur on your device, on our controlled servers, and/or via vetted third-party model providers operating under contractual data-protection commitments.
• We do not use your photos or other User Content to train any machine-learning or AI model — whether our own models or third-party models. Models are used only to process your content at runtime to deliver the features of the Service. We also do not use your content for advertising profiling.
• AI-generated outputs are best-effort interpretations and may be inaccurate or incomplete. They are intended for personal, non-authoritative use.

5. Third-Party Services & Data Sharing

We do not sell your personal information. We may share information only as follows:

• Service providers. We work with vendors who help us host infrastructure, deliver email, run analytics, provide customer support, and process content with AI models. These providers act on our instructions and are bound by appropriate confidentiality and data-protection obligations.
• Legal & safety. We may disclose information to comply with applicable law, lawful requests by public authorities, to enforce our Terms, or to protect the rights, property, or safety of users, the public, or us.
• Business transfers. If we are involved in a merger, acquisition, financing, or sale of assets, information may be transferred as part of that transaction, subject to standard confidentiality obligations.

6. Data Storage & Retention

We store your information on infrastructure operated by us or by our service providers. We retain personal information for as long as needed to provide the Service, comply with our legal obligations, resolve disputes, and enforce our agreements. Imported photos and derived outputs are retained while your account is active; you can request deletion at any time as described below.

7. Your Rights & Choices

Depending on where you live, you may have the following rights regarding your personal information:

• Access. Request a copy of the personal data we hold about you.
• Correction. Ask us to correct inaccurate or incomplete data.
• Deletion. Ask us to delete your personal data and account.
• Objection / restriction. Object to or restrict certain processing of your data.
• Portability. Receive your data in a structured, commonly used format.
• Withdraw consent. Withdraw any consent you previously gave, without affecting prior lawful processing.

These rights generally reflect protections under the EU General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA / CPRA), and similar laws. To exercise any of these rights, email us at [email protected]. We will respond within the timeframes required by applicable law.

8. Children’s Privacy

Seenful is not intended for children under the age of 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children. If we learn that we have collected personal information from a child without verified parental consent, we will delete it.

9. Data Security

We use reasonable administrative, technical, and physical safeguards designed to protect your information, including encryption in transit, access controls, and monitoring. No method of transmission or storage is 100% secure, however, and we cannot guarantee absolute security.

10. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date at the top and, where appropriate, provide additional notice (such as via email or in-product notification). Your continued use of the Service after the changes take effect means you accept the updated Policy.
