deja privacy policy

Last updated: 11 October 2026

deja is a Chrome extension that lets you search the posts you saved on Instagram, X, YouTube, Pinterest, Reddit, LinkedIn and TikTok. This page says what it does with your data. The short version: your saves never leave your computer.

What deja can't see

• deja can't see what you saved.
• deja can't see what you type or search for, unless you choose to send a search (see below).
• deja can't get into your accounts. It never sees or asks for your passwords.

deja runs on your device. The search, the AI and your library all live in your browser.

What deja reads

• When you press Sync for an app, deja reads the list of posts you saved there. It reads it through that app's own website, in a tab where you're already logged in. deja never sees or asks for your password.
• For each saved post it keeps what's needed to find it again: the caption, the author, the link, the picture's thumbnail, the song, the place, and the collection you saved it in.
• deja also listens to and reads the videos you saved, so you can search by what was said or shown in them. This happens on your computer too.

Where it goes

• Everything stays in your browser, in Chrome's storage on your computer. It is never sent to us or to anyone else.
• Search, picture matching, listening to reels and answering questions all run on your computer.
• deja has no account and shows no ads. Your saves are never sent to a server.

Helping deja get better

To know what to improve, deja counts which of its features get used. For example: how often the panel opens and for how long, how many searches find something, what kind of thing people look for (food, places, music: worked out on your computer, never the words), which result people open, and which apps are synced.

• These are counts and labels only. They never include what you saved, links, names, accounts or the words you typed.
• They come with the kind of computer (system, Chrome version, memory, whether it has a graphics chip, screen size) and the country. deja's server works the country out from the connection and doesn't store the IP address.
• They're tied to a random number made by your browser, not to you, so deja can tell "one person opened it 5 times" from "5 people opened it once".
• They go to deja's own server, run on Cloudflare.
• You can switch this off any time: deja's menu → Help improve deja. Switching it off also deletes counts still waiting to be sent.
• In Europe, deja asks before counting anything.

Only if you choose:

• Send us this search. When a search finds nothing, you can send that one search, so deja learns what it missed. Only that search goes, and only when you tap.
• Also share my searches. Off unless you turn it on in Help improve deja. Then your searches are sent, so deja can see what it gets wrong. Your saves still aren't.
• Your email, if you type it in for early features. deja only writes to you about deja. To remove it, clear it in Help improve deja or write to us.
• Why you left. If you remove deja, Chrome opens a short page asking what went wrong. Answering is up to you.

Voice

• When you tap the mic, deja listens only while the mic is lit.
• Your voice is turned into words on your computer, by Chrome's on-device speech recognizer or by deja's own speech model. It is never recorded, kept or sent anywhere.

What deja downloads

• Thumbnails and videos of your saved posts, straight from the apps' own servers, so it can show and understand them.
• AI models, downloaded once and then kept: a speech model from Hugging Face (for listening to your saved videos), and Chrome's own built-in model (only if you turn on answers). Downloading a model sends nothing about you or your saves.

Bug reports

Besides the counts above, only if you choose to send a bug report from deja's menu. It opens a form on Tally (tally.so), and you can read what's attached before you send it. The report holds technical details: counts of saves per app, error messages and settings. It doesn't hold your saved posts. Your last few searches are included only if you tick that box.

Deleting your data

• Forget everything in deja's menu deletes everything deja has stored.
• Removing the extension from Chrome deletes it all too.
• Your posts on Instagram, X and the other apps are never changed.

Children

deja is not made for children under 13.
