Summe

Terms of use

Summe · Last updated 15 October 2026 (v1.0)

Short version: Summe is a tool to design and export invoice and quote PDFs. Your data stays with you, Pro is a one-time purchase, and you are responsible for the documents you send.

What Summe is

Summe is a web app made by Studio Santé that helps you design and export invoice and quote documents as editable PDF files. By using Summe you agree to these terms.

Free and Pro

Summe can be used for free. Summe Pro is a one-time purchase that unlocks extra features (such as more designs and languages, no watermark and sync between devices) on the number of devices stated on the pricing page. It is a personal license: please do not share or resell your license key.

Purchases are processed by Lemon Squeezy, which acts as the seller (merchant of record) and issues your receipt or invoice. Prices and taxes are shown at checkout.

Refunds

If Summe Pro does not work for you, write to us within 14 days of your purchase and we will refund you. Refunds are made through Lemon Squeezy.

Your data and backups

Your invoices, clients and settings are saved in your own browser and, if you turn on sync, in your own Google Drive. We do not store them and cannot recover them. If you clear your browser data or delete the file in your Drive, that information is gone. Keep your own copies of the documents you send — for example, download your data from Settings from time to time.

Your invoices and your country

Summe is not a certified invoicing or accounting system and does not submit anything to any tax authority. Tax names, rates and numbering are set by you. You are responsible for the content of your documents and for meeting the tax and invoicing rules of your country — for example, some countries require certified invoicing software or e-invoicing for certain businesses (such as Verifactu in Spain). If in doubt, check with your accountant.

Fair use

Do not use Summe to create false or misleading documents, or for anything illegal. Do not try to break, overload or reverse-engineer the service or its license checks.

No warranty and liability

We work hard to keep Summe reliable, but it is provided “as is”, without warranties of any kind. To the extent permitted by law, Studio Santé is not liable for indirect losses, lost data or lost income, and our total liability is limited to the amount you paid for Summe Pro. Nothing in these terms limits rights you have as a consumer that cannot be excluded by law.

Changes

We may update Summe and these terms. If we make important changes, we will update the date at the top of this page. Features may change over time, but a Pro license you have bought will not be turned into a subscription.

Law

These terms are governed by Spanish law.
