Your photos and your data

What it keeps

• Your account: your name, email, and a scrambled form of your password (never the password itself), your business's name, city and state, and how much refinishing you've done.
• Your pieces: the photos you add, the painted versions made from them, and what you type about each piece: its size, costs, what you paid and sold it for, where it sold, the time it took, and notes.
• Receipts and expenses you add, with the receipt photos.
• Your helpers: the name and email of each person you invite.
• What the AI cost, per piece and per month, for your plan's allowance.
• Notes you send with Send feedback, with the screen you were on and the kind of phone or computer.
• Reports of errors your screen runs into: which screen, the kind of phone or browser, and the error itself. Never anything you typed, and never a photo.

To keep you signed in, the site sets one cookie, for up to 30 days. Your phone or computer also remembers a few of your choices, like whether keyboard shortcuts are on; those stay on that device. There are no advertising or tracking cookies, and no analytics service.

How it's used, and what goes into AI

• To run the app for you: your pictures, estimates, listings, costs and profit. AI services make your pictures, listings and receipt readings from your photos and receipts.
• To make price estimates better, and to improve the app, Sandpaper Sunday uses AI services with these kinds of data from every business: the kind of piece, its size, wood and condition, colors and finish, what was paid for it, what it sold for and where, costs, time spent, how long it took to sell, and the city. It also looks at which screens are used, where people get stuck, and what goes wrong.
• Not put into AI for estimates or improving the app: names, emails, passwords, notes you type, receipts, or photos. Your photos are used only to make your own pictures and listings.
• What other businesses see: only combined figures, and only when one comes from several businesses' sales, so nobody's own numbers can be picked out.

The AI services Sandpaper Sunday uses are business services: they don't train their AI on what Sandpaper Sunday sends them, and don't use it for anything but doing the work and their own safety checks. Nothing is sold or shared.

Who sees it

• You, and the helpers you invite. Helpers see the pieces and sales, not your expenses, profit or settings.
• Other businesses on Sandpaper Sunday see nothing of yours. The app checks this on every request. At most they see combined figures, as described above.
• Sandpaper Sunday, the business that runs the app, sees your business's name, its owner's name and email, its city, how many pieces and people it has, and how much AI it used this month, and works with the combined figures. It doesn't look at one business's pieces, photos or money, except to fix a problem you ask about, or when the law requires it.

Where your photos and records go

A few companies run parts of the app. They handle your data only to do that:

• Vercel runs the website and stores the photos, privately: a photo opens only for someone signed in to your business.
• Neon keeps the database with your records.
• OpenAI does the AI work. When a new photo is read for free previews, when AI pictures are made or checked, when a receipt is scanned, and when listing text or a hardware look is made, that photo or receipt is sent to OpenAI. OpenAI doesn't use it to train its AI. It keeps it for up to 30 days to check for abuse, then deletes it, and the app asks it to keep no other copy. (How OpenAI handles what apps send it)
• Google (Gmail) sends the site's emails, such as sign-in links and password resets, once email is turned on.

These companies handle your data only to run the app. Your data is never sold, never used for advertising, and never shared with anyone else.

How long it's kept

• Everything stays while your business is open.
• A piece you delete is kept for a day, so a mistake can be undone, then deleted for good with its photos.
• Closing your business (Settings → Close business) deletes everything in it, photos included, a day later. Until then you can change your mind.
• Notes and error reports stay until Sandpaper Sunday clears them. The website's own logs last about an hour.
• The database company keeps short-term copies for recovering from an accident. They expire on their own.

What you can do

• Download everything at any time: Settings → Backups → Download everything (photos included).
• Change or delete any piece, photo, sale, cost or receipt.
• Delete it all by closing your business.
• Ask what is kept about you, or for something to be deleted: email support@sandpapersunday.com, or use Send feedback in the app's menu.

Using Sandpaper Sunday while it's being tested

• It's a test version. Things will change, and sometimes break. Keep your own copy of anything important (Settings → Backups).
• Pictures aren't promises. AI pictures and free previews show an idea of the finish. Real paint, light and wood look different.
• Numbers are guides. Price estimates, local market prices and time estimates are rough guides, not advice. You decide what to pay and what to charge.
• Your photos stay yours. By adding them, you let Sandpaper Sunday store them and send them to the companies above to do what you ask, and for nothing else.
• Your data and AI. You agree that the kinds of data listed under “How it's used, and what goes into AI” are used with AI services as described there.
• Add only photos you may use. Keep people out of them where you can.
• Paid plans and free trials. Nobody is charged without agreeing first. Before you start a paid plan, or a free trial of one, you'll see the price and, for a trial, the day it ends. A trial you don't cancel by then becomes the paid plan (for example, $20 a month), charged to your card every month until you cancel, and you're responsible for those charges. You can cancel at any time, and the plan stops at the end of the month already paid for. Prices may change; you'll be told before a new price applies to you.
• If the test ends, you'll be told ahead of time, so you can download your backup.
• Play fair. Don't try to reach another business's things, or to break or overload the site.
• As it is. Sandpaper Sunday is offered as it is while it's being tested. As far as the law allows, Sandpaper Sunday isn't responsible for losses from using it, such as a piece priced too low.
• For adults running a business, at 18 or older.
