Terms of use and purchase
These terms govern the use of PiOne and its apps (Zopi, Cowpi, Worpi, Yospi, Fanpi and Rippi) and the purchase of its plans and add-ons. You accept them when you create your account or make a purchase. Please read them carefully: they are written to be understood.
This is an English translation of the Spanish «Condiciones de uso y contratación». If the two versions differ, the Spanish version prevails.

1. Who we are
PiOne is a service of Cow Technologies, S.L.U. (tax ID B70608153), with registered office at Rúa de Muros 72C, 15896 Portela de Villestro, Santiago de Compostela (A Coruña), Spain, registered in the Mercantile Registry of A Coruña, volume 371, folio 195, number 1/2020/22.0. You can write to us at soporte@pi-one.app.
2. Who PiOne is for
PiOne is designed for self-employed people, professionals and businesses, for use in their business activity. By creating the account and by purchasing, you declare that you do so as a professional or on behalf of a business, and not as a consumer.
3. Your account
- A single account works for all six apps. The details you give us must be true and up to date, especially your tax details, because we use them to issue your invoices.
- Keep your password safe and do not share it. If you think someone knows it, change it or write to us. If you forget it, you can create a new one at cuenta.pi-one.app/recuperar.
- You are responsible for what is done with your account, including what is done by the people you give access to (for example, your employees in Worpi).
4. Plans and what they include
- Junior: free, no card required, in any of the six apps, with usage limits.
- PRO: one app of your choice, without the Junior limits. The other apps stay on Junior.
- PiOne: all six apps on PRO, with a single account.
There are only two possible purchases: PRO for one app, or PiOne with all six. You cannot have two individual apps on PRO; that is what PiOne is for.
Each plan includes every month an amount of artificial intelligence usage and of emails that your apps send to your customers. The included amount renews on the first day of each month, and whatever you do not use does not carry over to the next month. The amounts for each plan are shown in the shop and in the apps; if we change them, we will notify you as explained in section 16.
5. Prices and taxes
Prices are those shown in the shop at the time of purchase and do not include VAT, which is added when you are charged (currently 21%). PRO for each app currently costs €19/month, or €190/year.
6. PiOne launch price
- While the launch offer lasts, PiOne costs €38/month + VAT, or €380/year + VAT. The offer has no set end date.
- The price of PiOne is €99/month + VAT, or €990/year + VAT.
- We will notify you of the end of the offer at least 30 days in advance, by email and on the website and in the shop.
- If you pay monthly, from the first charge after the end of the offer you will pay the PiOne price. Before that charge you can cancel at no cost.
- If you paid for a year during the offer, you keep your price until the end of that year. On renewal, it moves to the annual price in force at that time, and we will notify you 30 days in advance.
- The end of the offer does not change the price of PRO for each app.
7. Payment, renewal and invoices
- Payment is made by card through Stripe, our payment provider. We do not see or store your card details.
- Plans are paid in advance and renew automatically at the end of each month or each year, depending on what you choose, until you cancel.
- If a charge cannot be made, we will try again over a few days. If it still cannot be made, your account goes back to Junior until you pay; your data is not lost.
- For each charge, Cow Technologies issues you an invoice with VAT, using the tax details you give us when paying.
8. Changing your plan
- From Junior to PRO or PiOne: at any time, from the «Mejorar» (Upgrade) button in the app or from the shop.
- From PRO to PiOne: when you buy PiOne, your PRO is cancelled and the unused part is deducted from your next payments.
- From PiOne to PRO or Junior: you cancel PiOne, keep it until the end of the paid period, and then buy the PRO you want or stay on Junior.
9. Cancelling
There is no minimum term. You can cancel whenever you want from «Gestionar mis compras» (Manage my purchases), in your account's shop. Cancellation takes effect at the end of the period you have already paid for: until then you keep your plan, and afterwards your account stays on Junior, with your data. The part of the current period is not refunded, unless the law requires it.
10. AI and email add-ons
- If what your plan includes is not enough, you can buy AI or email add-ons. They are available for accounts with PRO or PiOne.
- They are a one-off payment. What you buy is used once the amount included in your plan for that month runs out.
- What you buy does not expire while your account remains active. It is not refundable and cannot be transferred to another account.
11. Acceptable use
You agree to use PiOne lawfully. In particular, you may not:
- send emails or messages to anyone who has not given you permission or with whom you have no relationship (no unsolicited bulk sending);
- publish, store or send content that is unlawful, misleading or infringes the rights of others;
- try to get around the limits of your plan, access data of other accounts or damage the service;
- resell PiOne or copy its apps without our permission.
12. Your data
- The data you store in the apps (your customers, your invoices, your appointments…) is yours. You can ask us for a copy at any time.
- How we process your personal data is explained in the privacy policy.
- When you store personal data of your customers in the apps, you are the controller of that processing and Cow Technologies acts as processor, solely to provide the service to you. If you need it, we will provide you with the data processing agreement.
13. The service
- We work to keep the apps available at all times, and we make encrypted backups every day. Even so, there may be interruptions, for maintenance or for reasons beyond our control. If they are scheduled, we will notify you.
- We continuously improve the apps: we may change, add or remove features, without significantly worsening what you have purchased.
- Features using artificial intelligence suggest texts and replies that may contain errors. Review them before using them; whatever you send or publish is your responsibility.
14. Liability
We are liable for the damage we cause you by breaching these terms. Except in cases of wilful misconduct or gross negligence, our total liability is limited to what you have paid us in the twelve months before the event giving rise to it, and does not include loss of profit or indirect damage.
15. Suspension and closure of your account
- We may suspend your account if you seriously breach these terms, especially the acceptable use rules. Except in urgent cases, we will notify you beforehand and give you the chance to put it right.
- You can ask us to close your account whenever you want, by writing to soporte@pi-one.app. Before that, we will give you a copy of your data if you ask for it.
16. Changes to these terms and to prices
We may change these terms and prices. If the change affects you significantly, such as a price increase or a reduction in what your plan includes, we will notify you by email at least 30 days in advance. The change applies from the next billing period and, if you do not agree, you can cancel before then at no cost.
17. Governing law and jurisdiction
Spanish law applies. For any dispute, and unless the law provides otherwise, the courts of Santiago de Compostela have jurisdiction.
