Memtrove Privacy Policy
Last updated: 2026-10-14
Memtrove is developed by Mei Biaokui ("we"). Memtrove is a file and bookmark search tool that runs locally on your Mac. We do not collect or upload your files, your index, your searches or your usage. There is no telemetry, no crash reporting, and no advertising or analytics SDK.
1. Data that stays on your Mac
| Data | Location | Notes |
|---|---|---|
| Index (file names, paths, extracted text, semantic vectors, tags) | ~/Library/Application Support/Memtrove/loci.db |
Readable only by your user account (permissions 0600) |
| Settings and logs | config.toml and memtroved.log in the same folder |
Logs contain file paths and are likewise readable only by you |
| License state | license.json in the same folder |
Trial start date, license key, activation instance ID, end of updates period |
| Semantic model | models/ in the same folder |
Public model files downloaded from Hugging Face |
| App state | ~/Library/Application Support/app.memtrove.desktop |
Whether you have completed setup |
Deleting these folders deletes all of Memtrove's data. Memtrove only reads your files; it never modifies, moves or deletes them.
2. When Memtrove connects to the internet
Memtrove only goes online in the following cases, and each time sends only what that feature needs:
- Downloading the semantic model (once, when you click "Download model" during setup or in Settings): public model files are downloaded from Hugging Face (huggingface.co). The request contains none of your data; like any website, Hugging Face sees your IP address.
- License activation and checks (when you activate a key, then at most once a day while online): Memtrove sends your license key and an instance identifier to our sales platform, Lemon Squeezy. The identifier is the fixed text "Memtrove for Mac" when activating and the instance ID Lemon Squeezy assigned afterwards. No device name, user name, files or usage information are sent. Being offline does not affect a license that is already activated.
- Checking for updates (when you click "Check for updates" in Settings): Memtrove downloads an update manifest from memtrove.app, and the update itself if you choose to install it. The request contains none of your data.
- Fetching bookmarked pages (off by default; only after you turn it on in Settings): Memtrove visits the addresses in your bookmarks so you can search them by content. Those sites see your IP address, just as if you visited them yourself. Memtrove respects each site's robots.txt and limits how often it visits.
- Purchasing: the "Buy a license" button opens Lemon Squeezy's checkout page in your browser. Payment details are handled by Lemon Squeezy; we never see your card details.
3. Connecting Claude and other AI assistants
If you connect Memtrove to Claude Desktop, Claude Code or another app that supports MCP, that app can search and read your files' content through Memtrove. Memtrove itself sends nothing anywhere, but content the AI app reads is handled under that app's own terms (for example, Claude sends conversation content to Anthropic). You can mark folders as sensitive to limit what the AI can read, or remove Memtrove from the AI app's configuration at any time.
4. Information we receive from our sales platform
When you buy, Lemon Squeezy acts as the reseller (Merchant of Record), handling the order, taxes and invoices, and gives us the order details (name, email, country, product and amount). We use this only to provide your license, after-sales support and the bookkeeping required by law. We do not sell it or use it for advertising. Lemon Squeezy's handling of your data is governed by its privacy policy: https://www.lemonsqueezy.com/privacy.
5. Children
Memtrove is not directed at children under 13, and we do not knowingly collect personal information from children.
6. Your rights
You can delete all of Memtrove's data on your Mac at any time (see section 1). To access, correct or delete your purchase records, contact support@memtrove.app. If the law where you live (for example the EU, UK or California) gives you additional rights, we will handle your request accordingly.
7. Changes
When this policy changes we will update this page and its "Last updated" date. Significant changes will also be mentioned in the app's release notes.
