Scrolly's refund policy is a 90-day money-back guarantee with a full refund, listed on the official store. That is three times the 30-day window that is standard for devices in this category.
A screen-time device is not like a gadget you can evaluate on arrival. It works or does not work depending on whether your habits change, and habits do not change in two weeks. Thirty days tells you whether the novelty held. Ninety tells you whether you are actually on your phone less, which is the thing you are buying.
It also covers the period where most people quit. The common pattern is a strong first fortnight, a slump, and then either the habit sticks or it does not. A 30-day window closes right around the slump.
Treat it as a test with one variable: where you keep the tag. Keeping it in a pocket and keeping it in a drawer in another room produce completely different results from the same device. If the first month is disappointing, change that before you conclude the product does not work for you.
The policy is set by the store and can change, so check the current terms at the point of purchase rather than relying on this page.
