# Straight answers. > What’s free, what Pro costs, where your data lives, and what StudSheet will and won’t do. ## Plans and billing ### Is StudSheet free? For homeowners, yes, always: Sheets, saved jobs, the shopping list, the Tool Shed and build mode. For contractors, StudSheet Pro is free for 14 days with no card, then $49 a month at the founding price. Crew members a contractor invites never pay. ### What happens when my trial ends? If you haven’t subscribed, your contractor account turns read-only: your jobs, clients and documents stay to open, print and export, but adding and changing them needs Pro. Subscribe any time to pick up where you left off. ### How do I cancel? In the app: Me → StudSheet Pro → Billing and card. Pro stays on until the end of the month you paid for, and nothing is charged after that. ### Do you see my card? No. Stripe takes the card on its own page. StudSheet never sees or stores card numbers. ### I picked Pro by mistake. Can I go back? Yes. On Me → StudSheet Pro, tap “I’m not a contractor” (when you’re not subscribed) and the app goes back to homeowner mode. ## Accounts and your data ### Do I need an account? Not as a homeowner: Sheets, jobs, lists and the Tool Shed are saved on your device. Contractors make an account (your email and a 6-digit code, no password) so jobs sync between phone and computer and clients can sign and pay on their link. ### Where is my data? On your device, and in your account when you’re signed in, so your phone and computer stay in sync. We don’t sell your data. You can export it any time, and deleting your account deletes it. ### Can my crew see my prices? No. Crew logins see only the jobs you share with them, never prices, estimates or invoices. ## The Sheets ### Where do the numbers come from? Each Sheet’s math runs on your device and shows its work under “How we got this”, with the code section or manufacturer guide it relies on. Anything that isn’t a published rule is marked typical. Code notes are a starting point: confirm with your building department. ### Will it tell me how to wire a panel? No. For homeowners, electrical, gas, plumbing and HVAC systems, additions and load-bearing walls go to a page on what’s involved and how to get quotes. Pros get quantities, costs, permits and inspection checklists, never step-by-step wiring or gas instructions, and never invented structural sizing. ### Does it work in Canada? Yes. Set your province for the National Building Code, the CEC and provincial notes, and pick metric if you like. US store prices aren’t shown in Canada. ### What if my job isn’t on the list? 45 Sheets are live. For anything else, contractors sketch and price it on the job: a price sheet of your own price lines, each quantity typed or measured off a quick sketch (rooms, runs and counts in feet and inches), repeated for every floor if you need it. Tell us what you'd like as a Sheet of its own at [support@studsheet.com](mailto:support@studsheet.com). ## Clients, payments and quotes ### How do clients sign and pay? You send a link (text or email). The client opens it in any browser, no app or account, reads the estimate, signs with a finger, and pays the deposit. By Zelle, check or cash, you record it in two taps; by card or US bank account on the link, the money goes straight into your own Stripe account; StudSheet takes no fee. ### Where do quote requests go? Only to pros registered and verified in the app, at most 3 local pros per request. Pros see the job and the area; the homeowner’s contact goes only to a pro who responds. ## Apps and AI ### When is it on iPhone and Android? The apps are waiting for App Store and Google Play approval. Until then StudSheet runs in any browser at [app.studsheet.com](https://app.studsheet.com/), and you can add it to your home screen. ### Can I use it with ChatGPT, Claude or Gemini? Yes. Connect your account and your AI reads and updates your jobs, clients, invoices, crew and price book when you ask. [How it works](https://studsheet.com/ai). ### Who makes StudSheet?
