Privacy
Effective October 9, 2026
In short: your list stays on your device, there's no account and no bank login, and PerkShift doesn't use tracking or advertising tools.
What you enter stays on your device
Your phone carrier and plan, the number of lines, your cards and your subscriptions are saved in your browser's own storage on your device. They are not sent to us.
To delete them, use Start over in PerkShift, or clear this site's data in your browser settings.
No account, no bank login
PerkShift never asks for a password, a bank login or card numbers. You choose your cards from a list by name.
Shared links
When you copy a link to your list, the list is written into the part of the link after the # sign. Browsers don't send that part to a website's server, so we never receive it. Anyone you give the link to can open your list.
What our hosting provider sees
PerkShift is hosted by Vercel. Like any website, each visit sends standard technical information to the host so the page can be delivered and kept secure: your IP address, browser type, the page requested and the time. We don't use this to identify you or build a profile. Vercel's own privacy policy explains how it handles this information.
No tracking, advertising or analytics
PerkShift doesn't use advertising, analytics or tracking tools, and doesn't set cookies to track you. Its fonts and images are served from its own site, so a visit doesn't contact other companies.
Links to other websites
Steps for a saving may link to a provider's own website. Those sites have their own privacy policies. PerkShift doesn't currently use affiliate links; if that changes, this page and the link itself will say so.
Calendar reminders
Reminder files are created on your device and saved by your browser. We don't see them or your calendar.
Children
PerkShift isn't intended for children under 13.
Changes
If this policy changes, we'll update this page and its effective date.
