§ Legal
Privacy Policy
Last updated · 30 June 2026
The short version: Lattice is local-first. Your conversations are stored on your own device, inside your browser. We don't run servers that receive them, we don't have accounts, and we don't track you. There is nothing for us to sell, because we never have your data.
01 What Lattice is
Lattice is a Chrome extension that maps your ChatGPT and Claude conversations into a navigable library — a map, search, and "ask your own history" layer that runs on your machine. This policy explains exactly what it does and does not do with your information.
02 What Lattice stores, and where
As you chat, Lattice reads the conversation on the page you're viewing and saves a structured
copy locally, in your browser's own storage (the standard chrome.storage.local
and IndexedDB used by extensions). This includes prompts, responses, edits, conversation titles,
and timestamps, plus your Lattice settings.
- This data is written to your device and stays there. No Lattice server receives it.
- We can't read it, back it up, or recover it — only you have it.
03 What we don't collect
- No account. You never sign up. We don't ask for your name, email, or a password to use the extension.
- No analytics or telemetry. We don't track which conversations you open, what you search, or how you use Lattice.
- No selling or sharing. There's nothing to sell — we don't hold your data in the first place.
04 "Ask Lattice" and your own AI key
Ask lets you question your history in plain language. It needs an AI model to do that, and it uses one on your terms:
- You bring your own API key for the provider you choose — Anthropic (Claude), OpenAI, Google (Gemini), or Groq.
- Your key is stored locally in your browser and is sent only to that provider, only when you run a query.
- When you ask a question, the relevant excerpts from your captured conversations are sent to your chosen provider to generate the answer — exactly as if you had pasted them in yourself. That request is governed by your provider's privacy policy, not ours.
- If you never use Ask, no conversation content is ever transmitted anywhere.
05 Payments
Paid plans (Pro and Founding) are handled by Gumroad. When you buy, Gumroad processes your payment and billing details under its own privacy policy. We receive only what's needed to confirm your purchase (such as a license or receipt) and never see your full card details.
06 Browser permissions, and why
Lattice requests only what it needs to do its job:
- Access to chatgpt.com and claude.ai — to read the conversation on the page you're viewing so it can be mapped.
- Side panel, tabs, active tab — to show Lattice beside your chat and know which conversation is open.
- Storage — to save your map locally on your device.
- Alarms & notifications — for background syncing and the occasional reminder.
- Your chosen AI provider's API and Gumroad — used only for Ask, and for verifying a purchase, respectively.
07 Deleting your data
- You can delete any single conversation, or wipe everything, from inside Lattice at any time.
- Uninstalling the extension removes its locally stored data from your browser.
- Because your data lives on your device, you are always in control of it.
08 This website
uselattice.online is a static marketing site. It sets no tracking cookies and runs no third-party analytics. Standard, privacy-preserving server logs may be kept by our host for security and reliability.
09 Children
Lattice isn't directed to children under 13, and we don't knowingly collect personal information from them — or, frankly, from anyone.
10 Changes to this policy
If we change how Lattice handles data, we'll update this page and the date above. Material changes will also be reflected in the Chrome Web Store listing.
