Short and plain.
PowerSave works without an account. Here is what is kept, and where.
Only on this device.
Your plan, chores and preferences stay in this browser's localStorage. They do not leave your device to a PowerSave database. Clear site data and they're gone.
Email, plan and chores.
If you choose to sign in with a magic link, we store your email address, plan, chores, quiet hours, units and theme so they follow you across devices. That's all. Auth is handled by Supabase.
We don't sell your data.
Not your email, not your plan, not your chores. There are no ads in PowerSave. No analytics pixels, no marketing cookies.
One button.
Settings → Delete my data clears what's on this device and, if you signed in, your synced settings and account.
Open SettingsIESO public reports.
The Grid loads wholesale prices from IESO public reports. Advice on Today still comes from your rate plan, not the wholesale price. Wherever a wholesale number appears, we label it: “Wholesale market price. Not what you pay.”
Vercel + Supabase.
The site is hosted on Vercel (short-lived request logs for operations). Optional accounts and synced settings use a dedicated Supabase project. Report a problem opens your email app to northamericanInventory@gmail.com— nothing from that form is stored on our servers.
