Postfit terms of service
Last updated: 2026-11-11
These terms apply to the use of the Shopify app Postfit, offered by Jasper Reijnen, trading as Ecom Studio Nimma (Kwakkenbergweg 150-05, 6571 GB Berg en Dal, Nederland, Chamber of Commerce 96695536). By installing the app, you agree to them. Postfit is intended for business use.
1. What Postfit does
Postfit shows or hides a letterbox rate at Shopify checkout, based on the settings you enter per product. Postfit doesn't create shipping labels, ship anything or charge shipping.
2. Your responsibility
You decide how many products fit in a letterbox parcel and which rates your customers see. Check your carrier's dimensions and conditions. Postfit calculates with your settings and doesn't guarantee that a shipment fits through a letterbox or is accepted as letterbox mail by the carrier.
3. Plans and billing
Plans and prices are shown in the app and the Shopify App Store. You pay through your Shopify bill. Paid plans include a 14-day free trial. When you reach your plan's limit, Postfit pauses until next month; your customers then see your regular rates.
We may change prices. We announce a price increase at least 30 days in advance.
4. Cancelling
You can cancel any time by choosing another plan or uninstalling the app. Before uninstalling, clean up via Settings → Uninstall Postfit, so no letterbox rate is left behind.
5. Availability
We do our best to keep Postfit available at all times, but don't guarantee uninterrupted operation. If Postfit isn't working, your checkout keeps working; Postfit then temporarily hides nothing.
6. Liability
Our liability is limited to the amount you paid for Postfit in the 12 months before the damage. We are not liable for indirect damage, such as lost profit, extra shipping costs or returns.
These limitations don't apply in case of our intent or deliberate recklessness.
7. Changes
We may change these terms. We announce important changes in the app at least 30 days in advance. If you keep using Postfit afterwards, the new terms apply.
8. Governing law
These terms are governed by Dutch law. Disputes go to the competent court in the district where we are established.
9. Data processing
Insofar as Postfit processes personal data on your behalf (order data, see the privacy policy), we are the processor and you are the controller. We process that data only to make the app work and according to your instructions through the app's settings.
Everyone at our side with access to the data is bound by confidentiality. We take appropriate security measures (see the privacy policy) and report a data breach within 48 hours.
We only use the sub-processors listed in the privacy policy. We announce a new sub-processor in advance; you can object by cancelling.
We help you with data subject requests and audits by providing information. After the agreement ends, we delete the data (see retention).
