## What is LoveLetter?

LoveLetter is a companion writing application centered around letter correspondence.

You can set a title, relationship, and speaking style for a "fictional character" and communicate with them through letters. After you send your letter, the application will generate a reply using AI. The reply will be unlocked after a certain period, just like waiting for a real letter.

Optimized for Chinese users:

Xue Tao letter paper
Feihong random poems
【What you need to prepare】
• Register and create an API Key on openrouter.ai, then save it in the app settings.
• Your network needs to be able to access OpenRouter; you can enter the model ID in the settings (default example: deepseek/deepseek-v3.2).

【Privacy and Data】
• Letters and character settings are saved by default on your iPhone; the API Key is stored in the system keychain.
• Only when generating a reply will relevant text be sent via HTTPS to OpenRouter and the selected model service provider; the developer does not operate its own server for storing your communication content.
• For a complete explanation, please see the in-app settings and the privacy policy link on this page.

【Notifications】
• Optional local notifications can be enabled to alert you when a letter is ready to be read; notifications use vague wording and do not contain the full text of the letter.

【Important Notice】
• Replies are automatically generated by AI and are not written by a real person, nor do they constitute professional advice such as psychological counseling, medical, or legal advice. If you are in a mental health crisis or immediate danger, please contact local emergency services or professional organizations.

The app adheres to the standard EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
