The Chrome extension
MyDataPreserver does not upload evidence, read email or Drive content, collect passwords, or communicate with a MyDataPreserver backend. It has no analytics or telemetry. Workflow data is stored in chrome.storage.local, not Chrome Sync.
What is stored locally
- Random request and collection IDs, source names, timestamps, guide progress, and confirmed export settings.
- Custodian names or reference codes provided by a requestor, prepared instructions, and delivery methods.
- Local activity logs, multi-source collection groups, and manually updated requestor statuses.
Use a reference code when a name is unnecessary. Do not enter passwords, access tokens, evidence, or confidential case details into instruction fields. The extension does not verify custodian labels against service accounts.
Access to service pages
The Google Takeout guide runs only on takeout.google.com. It checks narrowly associated selection labels, states, and page headings to assist the guide; raw page text is not stored or logged. The other source guides open in an extension tab. They do not inject scripts into or inspect those service pages.
When you open a provider link or sign in, you connect directly to that provider under its own policies. MyDataPreserver does not create exports, download archives, or open archive contents.
Files and reports
Instruction JSON files are read locally, validated, and shown for review before you save them. They are not signed and their authors are not authenticated by the extension. Files and reports are not automatically sent to anyone. You choose how to share them.
Retention and deletion
Archiving retains a collection in local history. Clearing saved setup removes the plan for future collections, not collection history or tracker records. Uninstalling the extension removes its local records. Downloaded instruction files, archives, and saved reports remain separate copies until you delete them yourself.
Local activity records are not encrypted or tamper-evident. People or software with access to your Chrome profile may access or change them. There is no backend backup or cross-device synchronization.
This website
This site has no account system, evidence-upload form, advertising, or site-added analytics. Its pages do not use browser storage or set application cookies. When hosted on Cloudflare Pages, Cloudflare handles normal connection information, such as IP addresses and request details, to deliver and protect the site under its privacy policy.
Links to external services take you to websites governed by their own policies. Downloads from this website contain the extension; they do not send your export archives to this site.
Questions about a collection
Contact the person who requested your collection for scope, delivery, or retention instructions. See Support for product troubleshooting and known limitations.
