Privacy

Last updated: 2026-05-30

Nila is a Chrome extension that helps you discover people through your existing Facebook friend-of-friend network. Privacy is the design center, not an afterthought.

What stays on your device

• Your Facebook session cookies, used only by Chrome to authenticate the requests Nila makes on your behalf. Nila never reads, copies, or transmits these cookies.
• Profile data Nila scrapes from pages your own Facebook account can already see: names, photos, public bios, mutual-friend counts, friend lists. All of this is stored locally in your browser's IndexedDB. It does not leave your machine.
• Your preferences (age range, gender preference, city, free-text filters). Stored locally in chrome.storage.local. Not transmitted.
• Your swipe history (likes, dismissals, saved profiles). Stored locally. Not transmitted.

What leaves your device

The only outbound traffic from Nila goes to a small Cloudflare Worker proxy for three optional LLM-powered features:

1. Query parsing — when you type a free-text filter ("women in Tel Aviv into hiking"), the text is sent to the proxy → Anthropic Claude → returns a structured filter. Only the text you typed leaves your device.
2. Profile vibe summary — when generating intro context, a short text excerpt (bio + a few public post snippets) for a single profile is sent to the proxy → Anthropic Claude. No identifiers, no graph metadata.
3. Intro draft — when you ask Nila to draft a message, the target's first name + a short vibe summary + your own first name + bio are sent to the proxy → Anthropic Claude → returns a message draft. Used once, not retained.

Nila does not send to the proxy: friend lists, photos, IDs, swipe history, your Facebook session, or any data about people you have not specifically asked to draft an intro for.

The proxy logs are aggregate (counts, error rates) for rate-limiting and budget control. They do not contain message content.

Anonymous product analytics

Nila sends a small set of anonymous usage events to PostHog, a product analytics platform, so we can understand what's working and what to improve. Events are tagged with a random per-install ID — we do not attach your name, your friends' names, message text, or any social-graph data.

Examples of events sent: extension_installed, sidepanel_opened, onboarding_completed, swipe_right / swipe_left (with anonymized counters like degree-of-connection and whether a photo was present), intro_panel_opened, intro_sent_to_messenger, fb_health_alert, silent_scrape_self_complete.

You can opt out at any time: open Nila → ⚙ Settings → "Anonymous analytics" → check "Opt out."

Data we do not collect

• No tracking pixels. No browser fingerprinting.
• No third-party services beyond the LLM proxy and PostHog analytics described above.
• No advertising integrations.
• No marketing emails. Nila has no account system.

Permissions explained

• storage — store profiles, preferences, swipe history locally in your browser.
• sidePanel — render the Nila UI in Chrome's side panel.
• scripting — inject the page-world script that allows Nila to read Facebook's own data shapes.
• tabs — open friend pages in background tabs during discovery.
• cookies — read your c_user cookie value to identify which Facebook session is logged in (so we can exclude you from your own deck).
• clipboardWrite — copy intro message drafts to your clipboard so you can paste them into Messenger.
• host_permissions: *.facebook.com — operate only inside Facebook. Nila does not touch any other site.

Account deletion

Nila has no accounts and no server-side records. To remove all Nila data:

1. Right-click the Nila icon → "Manage extension" → "Remove from Chrome", OR
2. Open Chrome DevTools → Application → IndexedDB → delete the nila database, AND
3. Open Chrome DevTools → Application → Storage → Local Storage → clear chrome.storage.local for the extension.

Either action wipes Nila's local state completely.
