Is my car safe where it's parked?

When you tap I just parked, Sweep takes a single location fix and matches it against the city's street-sweeping map, which ships inside the app. It snaps you to the nearest block segment and works out which curb you're on. Nothing is sent anywhere; the matching happens on your phone.

GPS can drift indoors or when Precise Location is off. If the block Sweep picked looks wrong, tap it to search by street name and door number instead — for example, 1935 Lakeshore Ave.

Because the two sides of a block often sweep on different days, and a location fix can't reliably tell a curb from the one across the street. When the sides differ, Sweep asks once — and it describes them by what you can see or by the door numbers ("Lake side · theater marquee up the street", "odd numbers"), never by compass directions. If both sides share a schedule, it doesn't ask at all.

Trust the sign. Signs are what enforcement goes by, and they can change faster than the city's published data. Then tell Sweep: tap Sign says otherwise? on the verdict card, enter what the sign says, and Save what the sign says. Your block is corrected on your phone, alerts are rescheduled to match, and the correction sticks the next time you park there.

If you can, email a photo of the sign and the cross streets to stockdapphelp@gmail.com so the underlying data can be checked too.

Yes. The complete San Francisco and Oakland schedules are inside the app, and every verdict, countdown, and reminder is computed and scheduled locally. Airplane mode, no signal, underground — all fine. The one thing that needs a connection is finding your block from GPS, and a garage can defeat that; use the street-name search instead.

A few things to check, in order:

• Permission. In iOS Settings → Notifications → Sweep, make sure Allow Notifications is on and alerts are set to show on the lock screen.
• Time Sensitive. Sweep's warnings are marked Time Sensitive so they can break through Focus modes. That switch lives in the same Settings screen; if it's off, a Sleep or Do Not Disturb Focus will hold the alert until the Focus ends — which for a 2 AM sweep is too late.
• Focus modes. If Time Sensitive is off and you'd rather keep it that way, add Sweep to the allowed apps of your Sleep Focus.
• The reminder itself. In Sweep → Settings → Reminders, each alert (evening before, two hours, thirty minutes, all clear) has its own toggle.
• You moved the car. Tapping I moved the car cancels every pending alert for that spot, as it should.

If all of that looks right and an alert still didn't fire, email the date, the block, and your iOS version — that combination usually pins it down.

San Francisco (SFMTA street-sweeping schedule data) and Oakland (City of Oakland GIS). You never have to pick: Sweep works out the city from where you park, and the street search covers both cities at once. (Settings → City only sets the default and the data notes; switching it by hand clears the current parked spot.) Other Bay Area cities publish their sweeping data in very different shapes, so they're evaluated one at a time — if you'd like yours next, say so by email.

No. Location is read once, when you park, and only to find the block. Sweep doesn't run location in the background, keeps no history, and has no account, analytics, or third-party SDKs. The only network request the app ever makes is a weekly check for a fresher schedule file — a request that carries no identifier and no location. Your parked spot never leaves the phone.

Not a subscription. Sweep Plus is a single $3 purchase that unlocks a second car, the Harbor and Ember curb-card themes, and Longest Spot. Everything that saves you a ticket — the verdict, the countdown, all reminders, the Live Activity, widgets, and sign corrections — is free for everyone and always will be.

Sign in to the same Apple account you bought Plus with, then open Sweep → Settings → Sweep Plus → Restore purchases. Apple confirms the purchase and Plus unlocks on the spot. Because it's a non-consumable purchase, it also works on any other device on the same Apple account, including with Family Sharing if you've enabled it for the app.

The schedules are rebuilt from the cities' published data every week. Sweep checks about once a week for a fresher copy, downloads it in the background, verifies it, and reschedules your reminders if anything changed. You can see the date of the data you're running under Sweep → Settings → About the data.

Holidays are handled per city, because the rules differ: San Francisco suspends sweeping only on New Year's Day, Thanksgiving, and Christmas, while Oakland suspends on all observed city holidays. Sweep folds those into the countdown so a holiday week doesn't wake you for a sweep that isn't happening. Holiday calendars are reviewed yearly — and as always, the posted sign and any temporary "no parking" notices win.
