Terms of Sale

Version of October 2, 2026.

Who sells, and what

Cayer is sold by the sole proprietor (entrepreneur individuel) identified in the legal notice. These terms apply to the Cayer Pro subscription, which opens up in the app every handwriting style, every paper, every tool and highlighter, and voice notes, with 5 GiB of storage per account (2 MiB per page). The details of what Pro includes are on the pricing page as of the day you subscribe. Writing stays free without a subscription.

The price

Yearly plan

€24 per year, paid all at once.

Monthly plan

€2.99 per month.

These are final prices. VAT not applicable, French General Tax Code (code général des impôts), Article 293 B. A price change never affects a period you have already paid for; you would be told by email before your renewal, and you could then cancel.

Ordering and paying

You subscribe from the app, with your account. You pay by card on a page run by Stripe, our payment provider: you enter your card on Stripe’s page, and Cayer never sees it. The subscription is paid when you order, then at the start of each period. An invoice is emailed to you with each payment: it states the version of these terms you accepted.

Length, renewal, and cancellation

The subscription renews automatically for the same length, one month or one year, until you stop it. You can cancel at any time, in a few clicks, from your account in the app: “Manage or cancel my subscription.” Cancellation takes effect at the end of the period you have already paid for: you keep Pro until then, and nothing more is charged after that. You can also switch from one plan to the other in the same place.

Deleting your account also stops the subscription, right away, without waiting for the end of the period. Within the 14 days after you subscribe, you are refunded for the unused days, prorated. After that, the subscription is stopped with no refund for the current period.

On the yearly plan, you are notified by email before each renewal, with the date and how to stop it from renewing (French Consumer Code (Code de la consommation), Article L215-1).

If a payment fails, Stripe retries for a few days and Pro stays open in the meantime. If there is still no payment after these retries, the subscription stops and your account goes back to Free. Your notebooks stay yours: nothing is deleted.

Your right of withdrawal

You have 14 days from the day you subscribe to withdraw, without giving any reason (French Consumer Code (Code de la consommation), Article L221-18).

Pro opens right after you pay. By choosing your plan in the app, you ask for the service to start before the 14 days are over: the sentence that says so is written right under the plans. If you withdraw after that, you are refunded in full, except for the days already used, prorated (Article L221-25).

To withdraw, write to contact@cayer.fr, preferably from your account’s email address so we can find it. One clear sentence is enough. You can also use the model form provided by law (annex to Article R221-1):

Model withdrawal form

(Complete and return this form only if you wish to withdraw from the contract.)

To the publisher of Cayer, sole proprietor (entrepreneur individuel), SIRET 10751408500011, contact@cayer.fr:

I/We (*) hereby give notice that I/We (*) withdraw from my/our (*) contract for the provision of the following service: Cayer Pro subscription.

Ordered on:

Name of consumer(s):

Address of consumer(s):

Signature of consumer(s) (only if this form is notified on paper):

(*) Delete as appropriate.

The subscription stops right away, your account goes back to Free, and the refund reaches the card that paid within 14 days. Your notebooks stay where they are.

Warranty

Cayer must work as described. If Pro doesn’t work, write to contact@cayer.fr: the legal guarantee of conformity for digital content and services applies (French Consumer Code (Code de la consommation), Articles L224-25-12 and following). An outage or a maintenance shutdown can happen; it is fixed as fast as possible.

Your data

What is kept, why, and how to have it deleted is in the privacy policy. What you write in your notebooks belongs to you.

A disagreement

Write to contact@cayer.fr first: you will get an answer. If the disagreement remains, you can refer it, free of charge, to a consumer mediator (French Consumer Code (Code de la consommation), Article L612-1).

These terms are governed by French law.
