FAQ

The specification tool for the built environment. Plan materials, products, surfaces, and dimensions in a single desktop app, then print a clean spec sheet for handover. Projects live as .tinn files on your machine and export to PDF. No subscription needed to open or read your files.

Architects, engineers, interior designers, and builders who specify materials, products, and surfaces for a living. Solo practitioners and small studios are the main fit, though the Firm plan supports larger offices.

No. Projects open and save with no network connection. You only need an account for cloud features like the clip library or cross-device sync (Studio and Firm plans).

Your projects are .tinn files that live wherever you put them: your hard drive, Dropbox, a network drive. Tinn never uploads your project files to our servers. You own them, and they stay readable long after any subscription ends.

Three plans: Solo (€49/month), Studio (€99/month), and Firm (€249/month). During early access, all plans are 30% off and that price is locked for your first 24 months. See the pricing page for the full breakdown. You can cancel any time.

PDFs exported on the Free plan carry a small "Made with Tinn" credit in the page margin. It sits in its own reserved band, so it never crowds your spec content, and it appears on every page of every export. Paid plans (Solo, Studio, Firm) export clean PDFs with no credit and no margin reserved for one. If you'd rather not show the credit, upgrade on the pricing page. The credit was added in v0.2.0 alongside making Free unlimited on project count.

When you subscribe during early access, the 30% discount applies automatically at checkout. The rate is locked for 24 months from the date you subscribe, not just the first month. After 24 months, billing returns to the standard price. If you cancel before 24 months are up, the discounted rate doesn't carry over to a new subscription.

The Founding 50 is a one-time round of 50 individual seats at 70% off the Solo plan, locked for 24 months. It's for people who'll use Tinn while it's still growing and are willing to share feedback in exchange for a deeper discount. The 70% rate applies automatically at checkout while seats remain; once all 50 are taken, the regular 30% early-access pricing applies. We ask for three bug reports or feature requests through the in-app widget within 60 days, plus an optional 20-minute call about how you work. Seats are per-individual: if a five-person office signs up, that's five of the 50.

Download Tinn from the download page. Any download right now is early access. You can also request an invite on the home page to get notified when the next round opens.

Almost none. Your project files never leave your machine. The one exception is the client portal: if you use it, a snapshot of the shared project is routed through Tinn's servers to generate the web view. We also collect account information (email and display name) and anonymous crash and usage reports. See the privacy policy for details.

Email support@tinn.app. Include your OS version and Tinn version (Help → About inside the app) so we can reproduce the issue. There is no chat support or ticketing system. Email is the right channel.
