Is Pinterest Dark Mode & Theme Safe? — Extension Safety Profile

The extension only asks for “storage” and “alarms” permissions. Storage lets it save your chosen dark or light theme locally, while alarms can schedule automatic theme switching at certain times. It does not request host permissions like access to pinterest.com, so it cannot read or change anything on the website itself. For a simple cosmetic tool that modifies a single site’s appearance, this is a very limited and expected permission set.

Dark mode add-ons are generally low-risk, but users should handle them with the same care as any third-party tool for a specific website. An individual developer could later sell the extension or push an update that quietly adds broader permissions, so it is wise to review permissions after an update and keep an eye on what the extension can access. The developer’s privacy disclosures state data is not sold or used for unrelated purposes, which fits its minimal technical reach.

The safety score is high at 88 out of 100. Its strongest dimension, Maintenance & Ownership, suggests the extension is actively maintained with recent updates, lowering the risk of becoming outdated or abandoned. The weakest, Publisher & Identity, reflects the fact that the publisher is an individual without a well-known brand, which is common for hobbyist extensions and means trust must come more from its public track record than from institutional reputation.
