Privacy: everything stays with you

Where Chatsavo stores chats, why nothing goes to our servers, and how to download a JSON backup, restore it into an empty data store or delete local data.

The short version: the extension sends nothing to our servers. Chat texts, folders and the index are stored only in your browser.

What stays only with you

Data Where
Chat message text The extension's database in your browser
Chat titles, dates, links Same
Folders, pins, prompts Same. Optionally, an encrypted copy of folders, placement and prompts in the browser’s sync storage
Search index Same
Panel settings Extension storage in your browser

AI sites and other extensions can't see this data: it lives in Chatsavo's own storage, not the page's.

What goes to our servers

Nothing. The extension sends nothing to our servers. Chatsavo is free, all of it, so there is no account, no key, no license server and no checks.

We don't receive chat texts or titles, page URLs, browsing history, cookies, or anything about your AI site accounts.

The early version 0.1.1 sends nothing either, but it keeps housekeeping data for its built-in trial on your side: a random install ID in extension storage, and the trial start date also in your browser's sync storage. The current build does not create them and deletes both on update; "Delete all data" also erases them.

How Chatsavo reads chats

A small script on the AI site copies the chat-list and chat-content responses that the page already loaded on its own when you opened the site or a chat. It:

  • changes nothing in the site's requests or responses;
  • doesn't read or forward cookies or auth tokens;
  • makes no requests of its own to the AI site.

That's why Chatsavo only knows the text of chats you've opened. Titles from the site list can show up sooner. It has no effect on your account.

Alice has no separate chat list. The alice.yandex.ru page loads reply text from rpc.alice.yandex.ru itself. The extension sees that response inside the Alice page and does not ask for a separate permission on rpc.alice.yandex.ru. A chat shows up when you open it, or when its link is visible in the sidebar.

Site access

The current version asks for access to chatgpt.com, chat.openai.com, claude.ai, gemini.google.com, grok.com, alice.yandex.ru, chat.deepseek.com and perplexity.ai (including www.perplexity.ai). ChatGPT and Claude are supported. The panel on Gemini, Grok, Alice, DeepSeek and Perplexity is in this build; their support is in testing. The Alice page loads reply text from rpc.alice.yandex.ru inside alice.yandex.ru; there is no separate host permission. Version 0.1.1 only saw ChatGPT and Claude — that is an old build and should be replaced. Chatsavo can't see any other sites you visit.

In Firefox, the extension declares that it collects no data, and the browser shows this at install.

Folder sync

In Settings you can Push or Pull. Folders, chat placement, prompts, tags, bookmarks, chains and auto-file rules are encrypted. Chat texts and titles are not part of that copy and are not sent. The passphrase is not saved. Ciphertext sits in the browser’s sync storage: the browser carries it, not the Chatsavo server. Without the passphrase the copy cannot be read. Deleting a folder, tag, bookmark or rule on one computer does not delete it on the other.

Coming later

  • AI summary. Summarizing a chat means sending its text to a model through a server. That only happens when you click the button. Before the first use, Chatsavo shows a separate dialog explaining it and asks for your consent, and we will update the privacy policy first.

That feature stays off. The folder sync above does not send data to a Chatsavo server.

Analytics

Chatsavo doesn't send usage statistics today. If anonymous counters are ever added (no texts, URLs or personal data), they'll be off by default and on only with your consent.

Your data, your call

Downloading all local data as JSON is always available. Files up to 25 MB (26,214,400 bytes) are also restorable by this version. Larger files are still downloaded in full as data exports, but this version does not import them back. The file is processed only in your browser and is never uploaded to a server.

Download your data

Open Settings → Your data → Download everything (JSON). If the result is at most 25 MB, Chatsavo names it chatsavo-backup-….json and it can be restored by this version. If it is larger, the complete file is still downloaded as chatsavo-data-export-….json, but it is export-only in the current version.

The JSON contains data Chatsavo has already saved locally: chat titles and messages, folders, pins, and any tags, rules, prompts and saved searches. It does not include panel preferences or browser settings (or, in version 0.1.1, the trial state). The JSON file is not encrypted: anyone who has it can read the saved chats.

Restore from JSON

Restore is available only when the local data store is empty. It does not merge with or automatically overwrite existing data.

  1. Open Chatsavo Settings. Close ChatGPT and Claude tabs during the restore so the extension does not save new chats.
  2. Under Restore a backup, click Restore from JSON and select a Chatsavo backup of up to 25 MB (26,214,400 bytes).
  3. Wait for the file to be checked. Review its name, creation date and the number of chats, messages and folders in the preview.
  4. Click Restore data to confirm the import. Nothing is written before this step; choose Cancel to stop.
  5. Wait for the success message. The search index is rebuilt in your browser, and you can then reopen the AI sites.

If your data store already contains data, download it first and check the message after export. Only a file that Chatsavo reports as restorable should be treated as the backup you will use for this restore flow. To replace the current data with your chosen backup, go to Your data → Delete all data, confirm with Delete, then repeat the restore. This does not delete chats from the AI sites.

A file with the wrong format, invalid data or a size above the limit is rejected before anything is written. Use a Chatsavo backup; importing archives from other extensions or exports from the AI sites is not supported yet.

Delete local data

Settings → Your data → Delete all data removes folders, saved texts and the search index after confirmation. Your chats on the AI sites are not affected.

Uninstalling the extension also removes its data from the browser. Only version 0.1.1 leaves a copy of its trial start date in your browser's sync storage.

We don't

  • sell or share data with third parties;
  • show ads;
  • open our own pages unless you ask (except the welcome page right after install).
