Privacy Policy

1. Introduction

Claude Project Downloader ("we", "our", or "us") respects your privacy and is committed to protecting it through compliance with this policy. This policy describes the types of information we handle and how your data is processed when you use the Claude Project Downloader Chrome Extension (the "Extension").

2. Data Collection and Handling

We believe in data minimization and user privacy. All core file processing—including intercepting, converting, zipping, and downloading project files—happens entirely locally within your browser. This file content never leaves your device.

The Extension is free to use. Exporting files and chats works without paying anything, and it stays that way — there is no trial that expires. An optional Pro upgrade, monthly, yearly or one-time, removes the free tier's limits; it is bought through Freemius, and the current price is shown on our pricing page.

The payment itself happens on Freemius' own pages. Your card details are handled entirely by them and are never seen, transmitted, or stored by the Extension or by us. To switch Pro on afterwards, the Extension transmits only a key and a randomly generated installation identifier to our own licensing server. Keys issued during the period when checkout ran through BuyMeMomo, and the licenses bought briefly through Dodo Payments in July 2026, remain valid and are honored by that same server.

Licence re-check. While a key is entered, the Extension re-checks it in the background — about once a day for a one-time licence, every few hours for a monthly or yearly subscription (and more often just after its paid-up date passes, so a renewal is picked up quickly) — sending the same key and installation identifier to our licensing server. That is how a subscription that has ended, or a refunded purchase, stops, and how the panel knows when a subscription whose renewal you turned off will end. A check that fails because the server can't be reached changes nothing.

Offers. The side panel can show an offer, such as a seasonal sale or a yearly plan for subscribers. Every few hours the Extension downloads the current offer settings (sale dates and wording) from our licensing server; that request carries nothing about you. Which offers you have already seen, and how many exports and backups you made while subscribed (shown back to you if you turn renewal off), are kept only on your computer. When a subscriber opens an offer, the Extension sends their licence key to our licensing server and gets back a temporary code, valid for 7 days, so the offer page can prepare a checkout for that same key without the key ever appearing in a web address. If you take the “3 months free” offer, the server notes your licence’s id until the extra months have been added, then keeps a record that they were.

“Report a problem”. The side panel has a Report a problem button. Nothing is sent unless you write a note and press Send. A report contains: the note you wrote; your email address, only if you type one in (it is remembered in the Extension so you don't have to type it again); the Extension version and your plan (free or Pro); which screen you were on and what the panel was showing, such as the project name and how many chats and files it found; the last few error messages the panel displayed; and the random installation identifier. It never contains the content of your chats or files. The report goes to our licensing server on Cloudflare, which adds your browser's user-agent string and a shortened one-way hash of your IP address (to rate-limit abuse), keeps the report for up to one year so we can fix the problem, and emails it to the maintainer through Resend. If you gave an email address, we use it only to reply about that report. If our server can't be reached, the Extension offers to open the same report as an email in your own mail app instead.

“Send a note” (Lifetime owners). Nothing is sent unless you write a note and press Send. A note contains: what you wrote, your plan, the Extension version, and your licence key, which our licensing server uses only to look up which licence the note came from (the email to the maintainer shows that licence’s id and plan, never the key). The server keeps the note text, plan and version for up to 180 days, without the key or your IP address, uses a shortened one-way hash of your IP address only to rate-limit abuse, and emails the note to the maintainer through Resend. No name or email address is collected unless you write one into the note. The optional “Buy me a momo” tip opens BuyMeMomo’s own page in a new tab; the Extension sends it nothing.

If you uninstall: the exit survey and a short diagnostic summary. When the Extension is removed, Chrome opens our uninstall page. Its address carries the Extension version, the random installation identifier and, from version 1.21.2, a short diagnostic summary the Extension keeps on your computer while installed: what kind of Claude page the panel last opened on (for example "project", "chat" or "not a Claude page"), how many files and chats it found there, how many times the panel was opened, how many exports finished or failed, up to three short error codes (such as an HTTP status like 404, never the error text), days since installation, your plan (free or Pro), whether you use the side panel or the popup, and your browser family (for example Chrome, Edge or Opera). It never includes a web address, a project or chat name or id, or any content. Nothing in it is sent while the Extension is installed. If the uninstall page loads, it sends that summary, with the answer you pick and anything you choose to type, to our feedback server on Cloudflare, which adds your browser's user-agent string and a shortened one-way hash of your IP address (to rate-limit abuse). We use it only to find out why the Extension didn't work for people and fix it, and keep it for as long as it helps with that; ask us at the address below and we will delete it.

Our website counts how its own pages are used — the home page, the pricing and offer pages, the thank-you page after checkout, the plan-management, cancellation and uninstall pages. Each step records an anonymous event on our licensing server (Cloudflare Workers Analytics Engine): which page, which button or offer (for example "monthly plan clicked" or "reason: too expensive"), which free-tier limit or extension version brought you there if the Extension opened the page, and a random visit identifier kept in your browser's localStorage that resets after 30 minutes of inactivity. That is how we learn which pages and offers work. No cookies are set, no third-party analytics or advertising scripts run, and nothing you type — your email, licence key or written feedback — is included in these events. Events are kept for about three months. None of this happens inside the Extension.

Data Summary

3. Required Permissions

• activeTab:

  Query the active Claude tab to retrieve the project file list when the icon is clicked.

• downloads:

  Save generated ZIP/individual files to the device.

• storage:

  Store your licence key, your Pro status, the free-tier counters, your backup schedule, when your last backup ran, your folders, and which offers you have seen with your export and backup counts while subscribed, locally on the device. The search index lives in the Extension’s own local database on the device.

• alarms:

  Run the automatic backups you switch on (daily or weekly), re-check a Pro licence key (about once a day, every few hours for a subscription) so a cancelled subscription stops, and refresh the offer settings.

• offscreen:

  Build a “Back up everything” ZIP in a hidden extension page, so a backup keeps running after you close the side panel. The ZIP is built in your browser and saved to your Downloads folder; it is never uploaded anywhere.

• sidePanel:

  Show the export screen and the Library in the browser’s side panel, so they stay open during long exports.

• scripting:

  Re-inject the Extension's own content script into an already-open Claude tab after an update or reload, so you don't have to refresh the page manually, and run the bulk Move and Delete actions you choose inside that tab. It is only ever used on claude.ai.

• host_permissions: https://claude.ai/*:

  Read your projects, chats, Cowork tasks, files, and Claude usage-limit figures from your own signed-in Claude session — to export them, back them up, file and search them, show what fills a project’s context, move or delete the chats you select, and show the usage meter. This data is processed in your browser only and is never sent to us or anyone else.

• externally_connectable: https://claudeprojectdownloader.com/*:

  Let our own website, and no other site, pass your new Pro key to the Extension on the thank-you page after checkout, so Pro switches on without copying and pasting the key. The website can’t read anything from the Extension or from Claude through this.

4. Third-Party Services

Freemius is the checkout and license provider for the Pro upgrade. The purchase itself happens on Freemius' own pages; the Extension never handles your payment details. Where a key was issued by Freemius, that key is checked against the Freemius API solely to confirm it is valid. See the Freemius Privacy Policy.

Cloudflare hosts our licensing server. It receives your key and a randomly generated installation identifier when perks are switched on or re-checked, and stores them only for that purpose. It also receives and stores a problem report when you choose to send one, as described above. It also stores a shortened, one-way hash of your IP address to rate-limit abuse; that value cannot be turned back into your IP. It never receives the content of your chats or files, your downloads, or your Claude account details. See the Cloudflare Privacy Policy.

Resend delivers email, and is used for two things. If you ask us to email you a backup copy of your key, your address is passed to Resend to send that single message; it is not stored afterwards. When you send a problem report or a note, Resend delivers it to the maintainer's inbox, with your email (if you gave one) as the reply-to address. Your address is never added to a mailing list and never used for marketing. If you don't ask for a key backup or type an email into a report, no email address is collected. See the Resend Privacy Policy.

Dodo Payments issued licenses for a short period in July 2026 and is no longer used, and BuyMeMomo handled checkout between versions 1.9 and 1.11 and is no longer used either — since version 1.14 the Extension has no permission for that domain. The Extension does not contact either service, and no data is sent to them. Keys from both periods remain valid and are honored by our own licensing server.

Google Fonts serves the typeface used by the Extension’s side panel and welcome page. Opening them makes an ordinary font request to Google, which sees your IP address and browser like any web request; nothing from Claude, your downloads or your licence is included. See the Google Fonts privacy FAQ.

Additionally, the Extension interacts with Anthropic's claude.ai web interface to function. Your use of Claude is governed by Anthropic's own privacy policy and terms.

5. Changes to Our Privacy Policy

We may update our privacy policy from time to time if the functionality of the Extension changes. We will notify you of any changes by posting the new privacy policy on this page and updating the "Last Updated" date.
