▸FAQ
Sharing my LINE account feels a bit nerve-wracking. Is it safe?+
You can relax — TeruTeru only reads your anonymous LINE ID. We never touch your phone number or chat history. You can unlink anytime, and your data is wiped the moment you do.
Is the free plan actually enough on its own?+
Yes — most people are happy with just the free plan. One morning nudge plus three core alerts (rain, cold, heat) cover almost every day-to-day weather question.
Can I register more than one location?+
Right now, one account tracks one location. If you want to watch both, say, home and your parents' place, please drop us a note through the feedback form — we're weighing it for a future update.
Can I cancel whenever I want?+
Of course. You can cancel anytime from "Membership" in your profile. Premium stays active until your next billing date, and then you quietly drop back to the free plan — no friction.
Can I fine-tune when and how I get notified?+
With Premium, yes — up to three evaluation windows (morning / afternoon / evening), up to three delivery times, and per-rule thresholds you can tune to your own taste.
