These terms are an agreement between you and SheetStamp ("we", "us") for your use of SheetStamp: the API at https://api.sheetstamp.com, its documentation, and the account features of our WordPress plugin (together, the "Service"). By creating an API key or using the Service you agree to these terms. If you use the Service for a business, you agree on its behalf.
SheetStamp turns data you send into files: barcode label sheets, thermal printer files, barcode images, invoices and packing slips. We may add, change or remove features. If we remove a feature you pay for, we will give at least 30 days' notice by email.
You need a working email address to get an API key. Keep your key secret; you are responsible for all use of it. If a key is exposed, request a new one from the sign-up form, which cancels the old key. You must be at least 18 and able to enter a contract.
Each plan includes a number of units per calendar month (UTC). One label or barcode image uses 1 unit and one invoice or packing slip uses 5 units. Unused units do not carry over. Requests that fail are not counted. Paid plans are billed monthly in advance through Stripe and renew until cancelled. Prices exclude taxes, which are added where required. We may change prices with at least 30 days' notice by email; the change applies from your next renewal.
You can cancel at any time from the billing portal. Your plan stays active until the end of the period already paid for and then moves to the Free plan. Payments are not refunded for part-used periods, except where the law requires it or where the Service was unavailable to you for most of the period.
You must not: break the law with the Service; create labels or documents that are fraudulent or that pass off goods as someone else's; send data you have no right to send; try to get around unit limits or rate limits, including by opening several free accounts; probe, overload or disrupt the Service; or resell the Service itself as your own API without our written agreement. You may use the files you create for any lawful purpose, including commercial use.
You keep all rights in the data you send and the files you get back. You give us permission to process that data only to provide the Service. Our Privacy Policy explains what we handle and for how long. If the data you send includes personal data of your own customers, you are responsible for having the right to send it.
We work to produce barcodes that meet the relevant symbology rules, but scanning depends on your printer, label stock, print settings and scanner. Test-print and scan before relying on a label or printing in volume. We do not issue, verify or guarantee GTIN, UPC or EAN numbers; you are responsible for the values you send. Invoices and packing slips are built from the figures you provide and are not tax or legal advice.
We aim to keep the Service available but do not promise uninterrupted service. We may suspend an account that breaks these terms, puts the Service at risk, or has an unpaid invoice. Where reasonable we will warn you first.
The Service is provided "as is" and "as available". To the fullest extent the law allows, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose and non-infringement.
To the fullest extent the law allows, we are not liable for indirect, incidental, special or consequential loss, or for lost profits, revenue, stock or data, including the cost of misprinted labels or documents. Our total liability for all claims about the Service is limited to the amount you paid us in the 12 months before the claim arose, or US$50 if greater. Nothing in these terms limits liability that cannot be limited by law.
You may stop using the Service at any time. We may end your access for a serious or repeated breach of these terms. Sections that by their nature should continue after the agreement ends will do so.
We may update these terms. For changes that reduce your rights we will email account holders at least 30 days before they take effect. Continuing to use the Service after that date means you accept the changes.
These terms are governed by the laws of the State of North Carolina, USA, without regard to conflict-of-law rules. Courts located in the State of North Carolina, USA have exclusive jurisdiction, except that either party may seek urgent relief in any court. If you are a consumer, you keep any rights that your local law says cannot be waived.
