Prices per letter

From the page count and the resulting letter format, colour or black and white printing, the chosen shipping type, optional express, and the destination country. The final price shown includes printing, postage and service. Under § 19 UStG no VAT is shown.

Our terms, § 4 prices and payment

Through Stripe Payments Europe, Ltd., by credit or debit card or with Apple Pay. The amount is captured immediately when the payment is confirmed.

No. Every letter is paid for individually. No subscription, no prepaid balance, no token system.

Yes. After a successful payment an invoice PDF is created automatically, with a sequential number in the format FK-YYYY-NNNN and the § 19 UStG note. You can open it in the app.

The moment you confirm the order during checkout and the Stripe payment completes successfully.

Within Germany, around 95% of letters are delivered at E+3 and 99% at E+4, so three to four working days after posting. FrankKi factors weekends and public holidays into the deadline buffer. Internationally, transit time depends on the destination country.

Yes, worldwide. Local postal rates apply in the DACH region (Germany, Austria, Switzerland) and in several European countries (France, the Netherlands, the United Kingdom, Belgium, Luxembourg, Spain). To the rest of the world, delivery typically takes 4 to 18 working days.

Prices and destinations

Printing, enveloping and posting are handled by our fulfilment partner. Delivery is by post: in Germany by Deutsche Post AG, abroad by the respective delivery service in the destination country.

Kompaktbrief, Standardbrief or Großbrief, the German compact, standard and large letter formats. The format is determined automatically from the page count, so you do not have to pick one.

Standard letters have no tracking number. You see the status of your letter in the app: ordered, printed, sent. After posting we also show the estimated delivery window. Real tracking with proof of delivery comes with registered mail.

More on registered mail

Yes. FrankKi sends status updates as push notifications, provided you allowed them.

In the app, on the letter itself. The invoice and the chosen shipping type are stored there too.

All features

Two of them. Einwurf-Einschreiben is delivery with a proof of posting receipt and without a signature, from €7.59. Übergabe-Einschreiben is personal handover against the recipient's signature, from €8.19. Both come with tracking.

It depends on how much proof you need. For most deadline-bound letters, Einwurf is enough. If the recipient has to sign in person, choose Übergabe.

International registered mail is available depending on the destination country. Which shipping types your address supports and what they cost is shown while you create the letter, before you pay.

Prices per letter

Only until your letter has been handed to our fulfilment partner for printing and posting after the payment cleared. From that point the service has been fully performed and the right of withdrawal lapses under § 356 (4) BGB. So get in touch as early as you can.

Right of withdrawal in full

With a clear statement, for example a letter or an email to support@frankki.app. A model withdrawal form is available, but using it is not mandatory. Sending the statement before the deadline expires is enough to meet it.

Model withdrawal form

Refunds run through Stripe back to the original payment method, without undue delay and at the latest within fourteen days of the day your withdrawal reached us. Depending on your bank it can then take a few more working days to show up.

Then we refund the full amount through Stripe and tell you by push notification. That covers technical faults on our side and a rejection by the fulfilment partner before printing and posting.

You are responsible for the accuracy and completeness of recipient data. If the letter was properly transmitted, printed and posted but delivery fails because of an incorrect, incomplete or undeliverable address, there is no claim to redelivery or a refund.

Orders that breach the obligations in § 6 of the terms can be rejected. Amounts already paid are refunded in full in that case.

Our terms, § 6 user obligations

Yes. Registration and authentication run through Sign in with Apple. The usage contract is concluded with that registration and your acceptance of the terms.

Letter drafts 180 days, letter PDFs until printing is finished, session tokens 30 days, server logs 14 days. Invoices are kept for 10 years because of the statutory retention duty (§ 147 AO).

Privacy policy with all retention periods

In the app under Profile, Delete account. Or by email to datenschutz@frankki.app. Account, addresses, letters, orders, payment references and device tokens are then deleted irreversibly. Invoices are subject to the statutory retention duty and remain stored.

Access, rectification, erasure, restriction of processing, data portability, objection and withdrawal of consent. Write to datenschutz@frankki.app. The competent supervisory authority is the Berlin Commissioner for Data Protection and Freedom of Information.
