Yumor Privacy Policy

Effective date: August 18, 2026

Last updated: October 11, 2026

We respect and protect the privacy of all users. To provide you with better services, this app (the "App" or "Service") has established this Privacy Policy ("Policy") to explain how we collect, use, store, share, and protect your personal information.

By using our Service, you agree to the collection, use, and processing of your information as described in this Policy. This Policy applies to all services you use through the Yumor App.

1. Scope

This Policy applies to the services we provide while operating this App. It does not apply to other websites or apps reached through links, whose content and privacy practices we cannot control.

2. Information We Collect

When you use this App, we may collect or process the following types of information:

• Content you create:
  • Notes and summaries: Notes, summaries, to-dos, tags, notebook categories, and attached images you create in the App are stored locally on your device by default.
  • Preferences: Theme, appearance, reading font size, sync settings, and reminder settings are stored on your device.
• Information sent for AI features:
  • Data sent: When you use AI summary, AI brief, polish, expand, continue writing, translate, extract to-dos, or AI Q&A, the note titles, note content, or selected text related to your request are sent (for AI Q&A, your question and the summary content are also included).
  • Recipient: Our official server, and the third-party AI service provider DeepSeek (deepseek.com). Data is sent from your device over an encrypted HTTPS connection to our official server, which forwards it to DeepSeek for processing and returns the results to you.
  • What our server does: It only forwards requests and counts usage (to enforce the daily usage allowance). We do not record your note titles, note content, or selected text, and we do not use it for any other purpose. We route through our server rather than letting the App connect to DeepSeek directly in order to keep the AI service credential out of the client — a credential shipped inside the App can be extracted by reverse engineering, which would put service availability at risk for every user.
  • Device identifier: The App generates a random device identifier (a UUID stored locally on your device) and sends it with AI requests to our server, solely to enforce the daily usage allowance and prevent abuse. It is not linked to your name, email address, or Apple Account, and it is not used for cross-app tracking.
  • Purpose: Solely to fulfill the AI request you initiate (summary, brief, polish, expand, continue writing, translate, extract to-dos, Q&A, etc.). We do not store this content on our servers.
  • Consent mechanism: Before you use an AI feature for the first time, the App clearly discloses this data sharing (what data is sent, who receives it, and why) and only sends data after you explicitly agree. You can withdraw consent at any time in Settings → AI Features; after withdrawal, AI features will not send any content to third-party services.
• Device permissions:
  • Camera: Used to take photos for notes (only when you initiate it).
  • Microphone and speech recognition: Used for voice input (only when you initiate it; recognition runs on-device).
  • Notifications: Used for daily review reminders (only if you enable them).
• Information processed via Apple services:
  • iCloud sync: When enabled, notes, summaries, images, and backups sync across your devices via Apple iCloud, subject to Apple's privacy policy.
  • In-app purchases: Subscription transactions are handled by Apple StoreKit; we do not directly collect your payment information.

3. How We Use Your Information

• Core services: Store, display, search, and sync your notes and summaries; generate to-do lists and statistics.
• AI processing: Send text you submit to the AI provider to fulfill summary, polish, translation, and similar requests.
• Backup and restore: Create backups locally or in iCloud for your use.
• Reminders: Send local notifications for daily review when you authorize them.

4. Storage and Security

• Retention: Notes and settings are stored on your device by default; with iCloud sync enabled, data is also stored in your iCloud account. We do not store the AI request content you submit — our server only forwards it and does not record note titles, note content, or selected text. After AI processing, the third-party provider handles data per its own policy.
• Retention of usage records: To enforce the daily usage allowance, our server records AI usage (device identifier, request count, and token consumption). Records containing a device identifier are retained for 30 days and then deleted automatically; daily aggregate statistics, which contain no identifier, are retained for 365 days. This cleanup runs automatically on the server.
• Security: AI requests are transmitted over HTTPS end to end (your device → our server → DeepSeek). Our server does not store request content, and the AI service credential exists only on the server and is never shipped with the App. As a third-party AI provider, DeepSeek's data processing is governed by its official privacy policy (DeepSeek Privacy Policy), which provides the same or equal level of data protection as this Policy. We recommend setting a device passcode and securing your Apple ID.

5. Sharing, Transfer, and Disclosure

• Sharing: We do not share your personal information with third parties except:
  • AI features: text you submit is forwarded via our official server to DeepSeek for processing (only to fulfill your request, and only after you explicitly agree in the App). Our server does not store this content. We have confirmed that DeepSeek provides the same or equal level of data protection as this Policy; its data processing is governed by its official privacy policy (DeepSeek Privacy Policy).
  • Apple services: iCloud sync and in-app purchases are provided by Apple, subject to Apple's privacy policy.
  • As required by law or with your explicit consent.
• Transfer: We will not transfer your personal information to any company, organization, or individual unless we have your explicit consent or are required by law.
• Public disclosure: We will not publicly disclose your personal information unless authorized by you or required by law.

6. Your Rights

You can manage your data by deleting notes, turning off iCloud sync, or uninstalling the App. Subscriptions can be cancelled in system settings. Contact us below for further assistance.

7. Children's Privacy

This App is not directed at children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us and we will delete it promptly.

8. Changes to This Policy

We may update this Policy from time to time. When material changes occur, we will notify you in the App or on this page.
