Privacy Policy

Last updated: 2026-04-22 · Extension: Evida (Chrome) · Contact: [email protected]

Summary

Evida is a Chrome extension that surfaces recent edits in Meta Ads Manager (who changed what and when). All data stays on your device. We do not run servers, we do not collect analytics, and we do not share anything with third parties except Meta's own Graph API — which you already authorize by pasting your own access token.

What data the extension handles

Data Where it comes from Where it's stored Why
Meta User Access Token You paste it in Settings chrome.storage.local on your device Required to call Meta Graph API on your behalf
User ID & name Fetched from /me endpoint once after you paste a token chrome.storage.local Powers the "Only my edits" filter
Ad account list Fetched from /me/adaccounts chrome.storage.local (cached for session) Populates the account dropdown
Activity log entries Fetched from /{account}/activities In memory for the popup; a local 7-day / 2000-entry cache may be stored in chrome.storage.local for alert previews Rendered as the change feed and alert dry-run previews
Settings You choose them chrome.storage.local User preferences (theme, refresh interval, active hours, filters)

All storage is local (chrome.storage.local). The extension does not use chrome.storage.sync — nothing is mirrored to your Google account or other devices.

What we do NOT do

Third parties

The extension can contact Meta Graph API (https://graph.facebook.com), Evida OAuth Worker (https://oauth.useevida.com) when you choose "Log in with Meta", and Slack incoming webhooks only when you explicitly configure a webhook URL. Meta's handling of Graph API requests is governed by their own Meta Platform Terms and Meta Privacy Policy.

Permissions explained

The extension requests the following Chrome permissions, each with a narrow purpose:

Data retention & deletion

All extension data lives in chrome.storage.local on your device. To delete everything:

  1. Go to chrome://extensions.
  2. Click Remove on "Evida".

Chrome will purge all extension storage. There is nothing stored elsewhere to delete.

To revoke your Meta access token independently, go to Meta's app settings and remove the app you generated the token with (typically "Graph API Explorer" or your own Facebook App).

Security

Data deletion

Because Evida stores data locally on your device, deleting your data is instant and does not require contacting us. You have two options:

  1. Disconnect from Meta and wipe local storage. Open the extension → Settings → Disconnect. This clears your access token and all cached campaign edits from chrome.storage.local.
  2. Uninstall the extension. Right-click the Evida icon in Chrome → Remove from Chrome. Chrome automatically purges the extension's storage on uninstall.

You can also revoke Evida's access token directly in your Meta Business Settings at any time — Evida loses all API access immediately.

If you authorized Evida via "Login with Meta" and want us to confirm deletion of any residual logs (short-lived token prefix hashes kept for rate-limit and abuse prevention, up to 30 days), email [email protected] from the email tied to your Meta account. We respond within 30 days per GDPR.

Children

The extension is intended for professional marketers managing their own (or their employer's / client's) Meta ad accounts. It is not directed at children under 13 and does not knowingly collect any information from them.

Changes to this policy

If the policy materially changes, the new version will be posted at the same URL and the "Last updated" date at the top will be revised. Material changes would typically coincide with a major version bump of the extension (e.g., 2.0.0).
