What you can do in ShiftProof on the web

Locked schedule snapshots

Type in the shifts as posted the day the schedule goes up; ShiftProof stamps and locks them with the notice window checked against your city’s 14-day rule.

Change log priced per ordinance

Log added, moved, hours-cut, cancelled, or sent-home-early shifts with how and when you were told — each one carries a live estimate and the rule citation.

All 12 rule packs, offline

NYC, Chicago, LA city and county, Philadelphia, Seattle, San Francisco, Berkeley, Emeryville, Evanston, Euless, and Oregon: notice windows, clopening thresholds, coverage, agency, and effective dates.

Owed Counter + share card

How many times the schedule changed in 30/90/365 days and the estimated predictability pay, with a breakdown by type, a changes-per-week chart, and a copyable card for the store group chat.

Clopening detector

Log closing and opening shifts; turnarounds under your city’s 9/10/11-hour threshold are flagged with the premium the ordinance attaches.

Evidence packet

A dated, downloadable packet — worker declaration, chronological change log with citations, clopening findings, and snapshot exhibits — organized the way NYC DCWP and Chicago BACP ask for it.

Your data

Lives in this browser. Nowhere else.

• Saved with your browser's local storage — never uploaded.
• Clearing site data, cookies, or history erases it permanently.
• Private windows forget it when closed.
• Another browser or device starts empty — nothing syncs.
• Export a JSON backup from the in-app menu any time; import it later.

What a phone app would add

• The iPhone app photographs the posted sheet or imports a screenshot; on the web you type the posted shifts into the snapshot instead, and the lock timestamp is your browser’s clock.
• The evidence packet and share card download as text rather than PDF/PNG — copy or download and attach them yourself.
• One job / one jurisdiction at a time; switching jurisdiction re-prices every logged change under the new rule pack.

Questions

Is the web version of ShiftProof free?+

Yes. Every screen is free to use: no subscription, no in-app purchases, no account.

Do I need an account?+

No. Open ShiftProof and start using it right away. Sign in with Google only if you want to upvote an app, save it to your list, or leave a comment.

Where is my data stored?+

Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.

Is there a ShiftProof app for iPhone or Android?+

Not yet. ShiftProof is a community proposal: the browser version is complete, and we build the iPhone and Android app once 100 people upvote it. Upvoters get one email when it ships.
