Why switch
CookieMaster vs EditThisCookie
EditThisCookie was abandoned and removed from the Chrome Web Store after MV3 landed. CookieMaster is MV3-native, ships with a confirmation dialog before bulk delete, and adds JSON import/export.
| Feature | CookieMaster | EditThisCookie |
|---|---|---|
| Monthly price | $2.99/mo | Free (with the trade-offs above) |

| Data leaves the browser | No — on-device by default | See competitor privacy policy |
| Ownership transfer risk | Aegis never sells extensions | Varies — see ExtensionWatch in this catalog |

Common questions
- Why does CookieMaster need cookie permissions?
- Listing, editing, and deleting cookies all require Chrome's `cookies` permission — there is no other API. The extension never sends cookie values to a server; everything happens in the browser.
- Can I export cookies and re-import them in another browser?
- Yes. JSON export captures the cookie name, value, domain, and flags. Import on another browser restores the exact cookie state — useful for sharing dev sessions across machines.
- Will deleting cookies log me out of every site?
- Bulk delete prompts for confirmation and lets you scope the delete to a single domain. Per-cookie delete only removes the cookie you click. There is no "delete all without warning" path.
- How does the Aegis Pro Pack unlock CookieMaster?
- Sign in to aegisfirma.com from any installed Aegis extension popup. The cookie-auth flow detects your active Pro Pack and unlocks Pro features instantly — no license key to copy or paste.
- Where is my CookieMaster data stored?
- CookieMaster stores everything in chrome.storage on your device. Your subscription record lives in our payment provider's account; we do not aggregate browsing or activity data.
- Can I cancel CookieMaster Pro anytime?
- Yes — billing stops at the end of the current period. Pro features remain active until the period ends, then drop back to the free tier.
- Why should I trust an extension I just heard of?
- Aegis extensions never change ownership and never sell user data. We publish security audit results and ship MV3-native code so Chrome itself enforces the permissions we claim.
