Features & Capabilities

Trimly is a subscription manager focused on privacy. It stores all data locally in the browser (AES-256), doesn’t send anything to the server, and doesn’t require an account.

What it does:

A catalog of 56 pre-configured services (streaming, music, VPNs, cloud storage, software, games, education, fitness, AI tools, and more) + the ability to manually add anything. Optional automatic plan detection when visiting a service’s website (reads only the website address; can be disabled with a single click). Self-updating billing dates—monthly cycles automatically roll forward. Tips panel: finds duplicates based on functionality (two VPNs, two cloud services, two chatbots, etc.) and shows the exact amount saved upon cancellation. Savings tracker: each cancellation is displayed as “Trimly saved you $X per year.” Backups: JSON, CSV, or encrypted JSON (PBKDF2 600k → AES-256-GCM) for cloud storage. Dark/light theme, payment calendar, catalog search. No external requests, telemetry, or accounts. Everything works offline.

Is Trimly — Subscription Manager Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Trimly — Subscription Manager requires a lot of sensitive permissions. Exercise caution before installing.
