MemVault — Privacy Policy

Effective date: July 2, 2026

TL;DR: Your memories never leave your browser. They are stored locally on your device and are never transmitted to us or anyone else. The only network communication MemVault performs is an anonymous license check with our payment provider if you upgrade to Pro.

What data MemVault handles

MemVault lets you save snippets of text ("memories") — content you select on web pages or type yourself — so you can insert them into AI chat services (ChatGPT, Claude, Gemini). This text is stored using Chrome's storage.local API on your device only.

What we collect

• No personal information
• No browsing history
• No analytics or telemetry
• No cookies
• No data is transmitted off your device by MemVault

Why MemVault requests its permissions

• storage — to save your memories locally in your browser.
• contextMenus — to offer "Save to MemVault memory" when you right-click selected text.
• Access to chatgpt.com, claude.ai, gemini.google.com — to show the memory panel and insert your chosen text into the chat box on those sites. MemVault does not read your conversations.
• Access to api.lemonsqueezy.com — solely to activate the license key of the optional Pro upgrade. See "Payments" below.

Payments (Pro upgrade)

The optional Pro upgrade is sold through Lemon Squeezy, acting as the merchant of record. Checkout happens entirely on Lemon Squeezy's website under their own privacy policy — MemVault never sees your payment details. After purchase you receive a license key; when you activate it, the extension makes a single request to Lemon Squeezy's license API containing only the key and a random instance name — none of your saved memories and no personal data. If you never upgrade, no payment servers are ever contacted.

Data sharing

We do not share, sell, or transfer any user data — we never receive it in the first place. Your memories exist only on your device, and you can delete them at any time from the extension popup or by removing the extension.

Exports

The Export feature saves your memories as a JSON file to your own computer. What you do with that file is entirely under your control.

Changes

If this policy ever changes (for example, if an optional sync feature is added), the change will be described here with a new effective date before it takes effect.
