Understand data retention and website deletion

Learn which history is pruned and how to remove a website's local data.

Last checked 21 August 2026

TechDash keeps most monitoring data locally while the website remains in the app. There is no single setting or general 90-day rule that removes every type of crawl history.

The 90-day rule that does apply

Alert-delivery records older than 90 days are pruned as new alert records are added. These records track that a failure or recovery notification event was created and which channels were involved.

This rule does not mean every incident, check result, screenshot, stored page, or Health Report point disappears after 90 days. Those records follow different parts of the local data lifecycle.

The 50-run limit for each monitored URL

TechDash keeps the most recent 50 check runs for each monitored URL. Each run includes its associated check results. When a new run takes the URL above that limit, TechDash removes the older runs and their results until only the latest 50 remain.

This retention is count-based, not age-based. An older run can remain for a long time when a page is checked infrequently, while a frequently checked page can pass through 50 runs quickly. Runs and results beyond the newest 50 are pruned regardless of whether they are minutes, days, or months old. There is no setting to increase this limit or restore a pruned run.

The 50-run limit is separate from the 90-day alert rule. Check runs record monitoring activity and results for one URL. Alert-delivery records track failure or recovery notification events and are pruned by age. Neither rule deletes the website itself, its current page state, or all other related records.

Data without one fixed age limit

TechDash does not promise one retention period for current page state, site-resource records, SSL, domain and DNS lookups, issue resolutions, ignored-check rules, Search Console data, or website health history.

Some current records are replaced when a newer observation arrives. Other history can remain while the website exists. Saved page HTML is managed as current or incident evidence, so do not assume every check creates a permanent full copy or that all saved evidence expires after a set number of days.

What website deletion removes

Deleting a website removes its related local database records and website data directory, including:

  • Monitored URLs, page checks, results, and current page state
  • Custom checks and site-resource records
  • SSL, domain, DNS, and related lookup records
  • Google Search Console connection, metrics, inspection data, and quota state for that website
  • Alerts, issue resolutions, ignored-check actions, and daily health history
  • Saved icon, screenshots, and compressed page HTML

There is no in-app recycle bin, archive, or restore action. Adding the hostname again creates a new website and new monitoring history.

Delete a website

Before continuing, save any incident details you are permitted to retain and check whether copies also exist in messages, exports, or backups.

  1. Open Websites.
  2. Open the correct website card's context menu.
  3. Select Delete Website.
  4. In the Delete website confirmation, verify both the display name and hostname.
  5. Read the message stating that the website will be removed from TechDash, including its screenshot and icon.
  6. Select the destructive Delete website button. Select Cancel if either identity is wrong.

Deletion succeeded when TechDash shows that the hostname was deleted and the website card disappears from Websites. If an older page for that website remains open, it can show Website not found after refreshing.

What deletion does not remove

Website deletion affects local TechDash data. It does not:

  • Modify or unpublish the live website
  • Remove pages from a search engine
  • Delete the Google Search Console property or revoke the Google account grant
  • Delete messages already sent to Slack, Microsoft Teams, or Discord
  • Erase copies retained by those providers or by operating-system backups
  • Revoke or unlink the TechDash license

Follow the relevant provider's deletion or revocation process for third-party copies. Follow your backup provider's retention and secure-deletion procedures if older local copies must also be removed.

Actions that preserve website data

Pause Monitoring stops new scheduled work but keeps the website, settings, incidents, history, Search Console connection, screenshot, and icon. Disabling one monitored page also preserves that page while stopping its scheduled checks.

Removing one monitored page is different from deleting the complete website. Unlinking a license also preserves website data. It clears the local license record, locks the app, and stops monitoring queues.

Uninstalling TechDash is an operating-system action, not the supported website deletion flow. Uninstaller and backup behavior varies, so do not use uninstalling as proof that a website's data was securely erased.

If TechDash cannot open, do not edit the database or manually delete only selected website files. Open https://techdash.com/support or Contact us before changing local data.

Crash-report retention is separate from website retention. The desktop app does not show a verified server-retention period or a list of uploaded reports.
