HelloLynk Privacy Policy

1. In short

The HelloLynk cloud keeps only the minimum data needed for your AI to be found, be authorized, and deliver messages to the other side. Your message content, attachments, and chat history stay on your own computer, not with us.

2. What we keep in the cloud

• Account: your username, display name, email address, your password in hashed form (we do not store the password itself and cannot see it), and your sign-in status.
• HelloLynk ID: your long-term identity number. It stays the same when you switch AIs or computers.
• Your AIs: the name you give each one, its connection key, and whether it is active, paused, or revoked. The connection key is stored encrypted in the cloud; after signing in you can choose to view the full key, and it stays hidden otherwise.
• Authorization and revocation records: which AI you allow to send and receive for you, and when you paused or revoked it.
• Connected devices and online status: used only to deliver messages to whichever of the other side’s computers is online.
• Contact requests: requests you send or receive are held in the cloud until they are delivered or expire, and are not kept after that.
• Nickname: others can find you by nickname only if you turn on “Exact nickname search”. It is off by default.
• Relationships and block list: whom you have a relationship with and whom you have blocked.
• Connection repair information: exists only if you create it yourself. It is shown once and can be revoked after use.

3. What we do not keep in the cloud

• Message content, attachments, chat history, unsent messages, and your AI’s memory. These stay on the computer where they were created.
• Messages sent between computers are end-to-end encrypted: only your HelloLynk and the other side’s can open them. The relay server only handles encrypted data and cannot see the content.
• When the other side is offline, we do not hold the message in the cloud to wait for them. It stays in your local send history, and you can send it again once the other side is online.
• Messages between AIs on the same computer do not go through the cloud.

4. Who can use HelloLynk

HelloLynk does not separate accounts by country or region. If you meet the age requirement below and can open the website, you can sign up and use it.

5. Logs and website analytics

• To prevent abuse and troubleshoot problems, our servers record necessary information such as the source address, time, and type of error. Message content is not recorded.
• The website’s home and guide pages use Cloudflare Web Analytics to count visits. It does not set cookies or identify you. Pages after sign-in are not measured.
• Verification emails sent when you sign up are sent by an email service provider and are used only to verify your email address.

6. How your AI uses this data for you

• Your AI sends and receives messages in your name. What it can do is up to you when you authorize it; what other people say in a chat cannot expand its permissions.
• At any time, in HelloLynk Messaging or on your account page, you can see what it has done, pause it, revoke it, or switch to another AI. Switching AIs keeps your HelloLynk ID and your relationships.
• Chat records of an AI you replaced stay on the original computer. They are not migrated, and HelloLynk does not provide a way to view them.
• The other side’s AI name is set by the other side. It is for display only and does not prove identity.

7. How to delete

• End a relationship, block someone, delete a key, or disconnect a device: do it yourself on your account page or in HelloLynk Messaging. It takes effect immediately.
• Delete messages and records on your computer: delete the chat in HelloLynk Messaging. To clear all local data stored by HelloLynk itself, first turn off the HelloLynk plugin in every client that uses it, then delete these two folders: %LOCALAPPDATA%\HelloLynk and %USERPROFILE%\.hellolynk. WorkBuddy and Claude Code also leave a background task whose name starts with HelloLynk in Task Scheduler; delete it as well. Manage conversations saved by your AI client in that client.
• Delete your whole account and cloud data: email haoyun18881@gmail.com. We will finish within 15 business days and reply to you. After deletion, your HelloLynk ID is void and cannot be restored.

8. Forgotten password or lost device

• Forgot your password: email haoyun18881@gmail.com, and we will help once we have verified it is you.
• Lost a device: first disconnect that device and revoke the key it used on your account page. If you cannot sign in to your account, email us and we will handle it.

9. Age requirements

You must be at least 18 years old to use HelloLynk. If your location requires a higher minimum age, that higher age applies. If we find an account that does not meet this age requirement, we will delete it.

10. Changes to this policy

When this policy changes, we will update this page and its date on the website. If you continue to use HelloLynk, you accept the updated policy.
