Privacy Policy

01Scope and who we are

This Privacy Policy applies to the Yisee mobile application for Android (package name com.yisee.app, the “App”) and to the backend service the App uses to generate analysis reports and manage purchases (the “Service”).

The App provides an I‑Ching inspired framework for reflecting on a situation. It is a self‑reflection tool; it does not provide medical, legal, financial, or other professional advice.

In this policy, “we”, “us”, and “our” refer to the developer of Yisee. You can reach us using the contact details in Section 13.

02Information we process

2.1 Content you provide

When you request an analysis, you enter a question (up to 300 characters) and three sets of three digits, and the App records your language and analysis mode. This content is transmitted to the Service to generate your report. Generated reports are stored on your device in the App’s local database.

2.2 Technical data generated by the App

Installation ID. On first launch, the App generates a random identifier (a UUID) and stores it in the App’s private storage. The App sends it in the X-Install-Id header on each request. We use it to keep track of credits, associate a verified purchase with an installation, and prevent abuse. It is not derived from hardware identifiers, is not used for advertising, and is replaced with a new random value if you clear the App’s data.

2.3 Purchase data

Purchases are processed by Google Play Billing. When a purchase is completed, the App sends the product ID and the Google Play purchase token to the Service. Our server verifies the token with Google, confirms the purchase, and records the result. We store the purchase token, a one‑way hash of that token (used to detect duplicate redemption), the related product ID, timestamps, and the credit balance associated with your installation ID.

2.4 Data processed automatically by our servers

When the App contacts the Service, our hosting infrastructure necessarily processes standard request information such as your IP address, the time of the request, and HTTP headers. Our application logs record a shortened installation ID, a job ID, and error information. They do not record the text of your question.

03Information we do not collect

The App does not request, and we do not collect:

• your name, email address, phone number, or postal address (we do not operate user accounts);
• your contacts, calendar, photos, files, microphone, or camera;
• precise or approximate location;
• the Android advertising ID, or any other advertising identifier;
• health, biometric, or financial account information.

The App includes no third‑party advertising SDK and no third‑party analytics or attribution SDK.

04How we use information

• To generate your report. Your question, digits, language, and mode are used to produce the analysis you requested.
• To manage credits and purchases. Your installation ID and purchase records let us confirm purchases, apply credits, and prevent the same purchase from being redeemed more than once.
• To operate and secure the Service. Logs and technical data help us keep the Service available, diagnose errors, and detect abuse.
• To support you. If you contact us, we use the information you provide to answer your request.
• To comply with law. We may process information where required by applicable law or to enforce our terms.

Where applicable law requires a legal basis, we rely on performance of our contract with you (providing the Service and the features you request), our legitimate interests (keeping the Service secure and preventing fraud), and compliance with legal obligations.

05AI processing and third-party model providers

Reports are generated by large language models. To produce a report, the App sends your question text, digits, language, and mode to our gateway at googleapi.sharkai.club. Our gateway composes a prompt and sends it to a third‑party AI model provider through an OpenAI‑compatible API endpoint.

We do not use your questions to build advertising profiles, and we do not use them to train our own models. Third‑party providers process the prompt under their own terms and privacy policies; we select providers that offer API services and require them to use the data only to deliver the requested output.

06Storage and retention

6.1 On your device

Analysis reports are saved in the App’s local database so you can review them later. You can delete individual records in the App, clear all records from the settings screen, or remove everything by uninstalling the App. Local data cannot be recovered after deletion.

6.2 On our servers

We retain installation IDs, credit balances, and purchase records (including the purchase token) for as long as needed to provide credits, verify purchases, and prevent duplicate redemption. Analysis jobs are processed in memory and are not stored in a database. Server logs are kept for a limited period for security and troubleshooting.

If you would like the server‑side data associated with your installation ID deleted, contact us as described in Section 13. Note that deleting this data may make unused purchased credits unavailable, and we may need to retain limited records where the law requires it or to resolve disputes.

6.3 Reinstalling the App

If you uninstall the App or clear its data, a new installation ID is generated the next time you open it, and credits associated with the previous installation ID may no longer be available. The App offers a Restore purchases action that asks Google Play for purchases that have not yet been consumed.

07Sharing and disclosure

We do not sell your personal information. We share information only in the following circumstances:

• Google Play. Payments are processed by Google. We use Google Play’s servers to verify purchases, and Google processes your payment and account information under Google’s Privacy Policy.
• AI model providers. Your question text and related inputs are sent to a third‑party model provider to generate your report, as described in Section 05.
• Hosting and infrastructure providers. Our Service runs on servers operated by a hosting provider that processes data on our behalf.
• Legal and safety. We may disclose information if required by law, legal process, or a valid governmental request, or where necessary to protect the rights, safety, or property of users or others.
• Business changes. If the App or the Service is transferred as part of a merger, acquisition, or sale of assets, information may be transferred as part of that transaction, subject to this policy.

08Security

We use HTTPS/TLS for communication between the App and the Service, keep purchase token hashes to enforce single redemption, restrict access to server‑side data and credentials, and keep our systems updated. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

09Children

The App is not directed to children. We do not knowingly collect personal information from children under 13 (or the minimum age required in your country). If you believe a child has provided information to us, contact us and we will take appropriate steps to delete it.

10Your choices and rights

• Delete local data. Delete individual reports in the App, clear all records in settings, or uninstall the App.
• Restore purchases. Use Restore purchases in the App to ask Google Play for purchases that have not yet been consumed.
• Request deletion of server‑side data. Contact us and include your installation ID (shown on the App’s settings screen). We will delete or anonymize the data associated with it, except where we must retain it for legal or fraud‑prevention reasons.
• Ask questions or raise a concern. Contact us using the details below; you may also have the right to complain to your local data protection authority.

Depending on where you live, you may have additional rights, such as the right to access, correct, or port your information, or to object to certain processing. Because the App does not use accounts, we can usually identify your data only through the installation ID.

11International transfers

Our servers, hosting providers, Google, and the AI model providers we use may be located in countries other than yours. As a result, your information may be processed in a different jurisdiction with different data protection rules. Where required, we rely on appropriate safeguards for such transfers.

12Changes to this policy

We may update this policy to reflect changes in the App, the Service, or applicable law. When we make material changes, we will update the effective date at the top of this page and, where appropriate, notify you in the App. Continued use of the App after an update means you accept the revised policy.

13Contact

For privacy questions, deletion requests, or other concerns about the App, contact the developer of Yisee using the developer contact email shown on the App’s Google Play store listing (search for “Yisee”, package com.yisee.app). Please include your installation ID if your request concerns credits or purchase data.
