If we change anything important in this text, we will tell you in the app before it applies. This is a translation: if it differs from the Spanish version, the Spanish version prevails.
Calma Terms of Use
Last updated: 5 November 2026
1. Who we are
Calma is a service of ARTIFICIAL INTELLIGENCE HACKS, SOCIEDAD LIMITADA (AIHacks-ES), tax ID (CIF) B05810908, with its registered office at Calle Escalonia 15, Portal 13, Bajo C, 28231 Las Rozas de Madrid (Spain), registered with the Madrid Companies Registry (Registro Mercantil de Madrid), sheet M-900408. Contact: soporte@aihacks-es.com and the telephone +34 617 731 325 (if we cannot answer, leave a message and we will call you back). Email is the fastest way to reach us.
Until 26 October 2026, while the company was being incorporated, Calma was a service of Alejandra Taborda Londoño. Your account, your data and these terms stay the same: only who provides the service changes.
2. What Calma is and what it is not
Calma looks at your calendar and suggests slots for you to rest and look after yourself, keeps track of your wellbeing goals and helps you plan your days off.
Calma is not a medical or psychological service. Its suggestions are general wellbeing suggestions, not a diagnosis, a treatment or professional advice. If you have a health problem, physical or mental, consult a professional. If you are in a crisis situation, call 112 or, in Spain, the 024 suicide prevention helpline.
3. Your account
- Anyone can create a Calma account, for free.
- You can register and sign in with your email and a password (we email you to confirm it), or with your Google, Apple or Microsoft account.
- You must be at least 16 years old, and you confirm this when you register. By creating your account you accept these terms.
- Your registration details must be your own and true. Your password is personal: if you think someone knows it, change it.
- You can download all your data from Settings → Download my data.
- You can delete your account whenever you want from Settings. Your account and everything Calma stores about you are deleted (see the privacy policy). If you have Calma Plus, read section 10.7 first.
4. Google Calendar and Outlook
Connecting Google Calendar or Outlook is optional.
If you connect Google, you authorise Calma to read your calendars, to create and change the events you manage from Calma in a dedicated calendar called "Calma", and to delete from Google the events that you delete from Calma. You decide in Settings whether Calma uploads changes on its own or asks you first. Calma does not delete your Google events unless you ask it to in the app: before deleting, it tells you that the event will also be deleted there, and for 7 days you can recover it from the Trash.
If you connect Outlook, you authorise Calma to read your calendars and to upload to Outlook what you schedule in Calma.
Google and Microsoft are third-party services with their own terms. Calma is not liable for what happens within your Google or Microsoft account, or for outages of or changes to their services.
5. Artificial intelligence
Some suggestions are generated by an AI model (Gemini, from Google), and the app indicates this. The AI can make mistakes: suggest something at a time that does not suit you or that does not fit your day. Nothing is scheduled without your accepting it, and you can edit or reject any suggestion.
There is a limited number of AI suggestions per day; after that, suggestions come from fixed rules within the app.
"Ask Calma" lets you ask for a slot in your own words. If the app does not understand the request on its own, the AI reads it, and it may misunderstand it: check what it suggests before accepting it. You can make 5 requests a day.
6. Verify with Health
In the mobile app you can turn on "Verify with Health" so that Calma checks with Apple Health or Health Connect whether you did the activities you scheduled. It is optional and off by default. Calma is not a medical device and does not interpret your health data: it only compares times. What it reads and what it stores is set out in the privacy policy.
7. The time-off planner
The planner suggests how to spread your holiday days according to the public holidays in your area. Public holidays may contain errors or change: check the plan with your employer and with the official calendar before requesting your holidays. Calma is not liable for the employment decisions you make with it.
8. Shared holiday plans
You can plan your days off with another person who has a Calma account. Invite only someone who wants to plan with you, and use an email that person knows. Each of you sees the plan and the other's first name, never their calendar.
9. Acceptable use
You may not use Calma to:
- access other people's accounts or data;
- try to get around the service's limits, overload it or attack it;
- automate requests to the service without permission, or extract its content in an automated or bulk way (scraping, bots or calling its API directly outside the app);
- decompile, disassemble, reverse engineer or try to obtain Calma's code, AI instructions or internal logic, except to the extent the law expressly allows it;
- copy or imitate the app, its features, texts, design or results to build or improve a product or service that competes with Calma, or help anyone else do so;
- create accounts in bulk, with false details or temporary email addresses, or share or resell access to your account;
- anything illegal.
If you do, we may suspend or close your account, telling you and explaining why unless we have to act immediately, and take the legal action available to us.
10. Plans and price: Calma Plus
10.1. The plans
Calma has two plans:
- Free. Everything described in these terms, with usage limits: a number of AI suggestions and of "Ask Calma" requests per day, and of times you can use the time-off planner. The limits at any given time are shown in the app.
- Calma Plus, paid. The same, with more AI suggestions per day, made with our best model, and the time-off planner as many times as you want. What Plus includes at any given time is described in the app before you subscribe.
Calma has no ads, and nobody starts paying without choosing it. If you do not subscribe to Plus, you stay on the free plan. To subscribe to Plus you must be an adult or have your parents' or guardians' permission.
Plus works wherever Calma works: on the web (current browsers), in the installable app and in the iPhone and Android apps, always with an internet connection and your Calma account. It has no technical protection measures that limit its use.
10.2. Price
Calma Plus costs €4.99 a month or €39.99 a year, VAT included: the same price throughout the European Union. Outside the EU the price is the same; if one day your country required us to charge a tax, you would see it on the payment screen before confirming. There are no other charges.
We may sometimes offer discount codes or free periods (for example, to people taking part in the closed test). Their conditions are stated when they are offered. A gifted Plus does not renew and does not charge you anything: when it ends, you go back to the free plan unless you subscribe.
If we change the price, we will tell you by email at least 30 days before it applies to your subscription. The new price applies from the next renewal; if you do not agree, you can cancel before then and you will not be charged.
10.3. Where you subscribe and who charges you
- On Calma's website (calma.aihacks-es.com). You are charged by ARTIFICIAL INTELLIGENCE HACKS, SOCIEDAD LIMITADA. The payment is processed by Stripe: Calma never sees your card details. We send you the invoice by email. It is a simplified invoice; if you need a full invoice with your tax ID, ask us at soporte@aihacks-es.com.
- Inside the iPhone or Android app, if your version of the app offers it, with App Store or Google Play in-app purchase. In that case Apple or Google sells it to you and charges you, under their terms, and the store gives you the receipt and handles renewal, cancellation and refunds. These terms apply to everything else.
Either way you get the same Calma Plus on all your devices, with your Calma account. There is no need to pay twice: if you already have Plus, the app tells you.
How you subscribe on the website. Sign in to Calma, open Settings → Your plan, choose the monthly or the yearly plan and press "Subscribe". You go to Stripe's payment page, where you enter your billing address and your payment method (credit or debit card, and any other method Stripe offers in your country), see the final price and can correct any detail before confirming. The contract is concluded when you confirm the payment. Within minutes we email you a confirmation of the contract, with the essentials of these terms and the withdrawal form: keep it. We also keep the record of your subscription for as long as you have the account, and you can ask us for it at soporte@aihacks-es.com. The contract is concluded in Spanish or in English, the language you use in the app; if there are differences, the Spanish version prevails.
10.4. Automatic renewal
Plus is a subscription that renews automatically at the end of each period (every month or every year, depending on what you choose), with the same payment method, until you cancel it. In Settings → Your plan you can see until when it is paid and whether it renews. If you have the yearly plan, we will email you a few days before it renews.
10.5. Cancelling
You can cancel at any time, without giving reasons:
- If you subscribed on the website: in Settings → Your plan → "Manage subscription", which opens the Stripe portal.
- If you subscribed in the app: from the subscriptions of your Apple or Google Play account.
If you subscribed on the website, you can also cancel by emailing soporte@aihacks-es.com from your account's email address.
When you cancel, you keep Plus until the end of the period you have already paid for, and then you go back to the free plan. You are not charged again. Outside the right of withdrawal (section 10.8), cancelling does not entitle you to a refund of the unused part of the period. You do not lose your data when you go back to the free plan.
10.6. Changing plan
You can switch from monthly to yearly, or the other way round, from the same place where you cancel. The change applies immediately: if you switch to yearly, you pay the difference straight away, minus the unused part of the month; if you switch to monthly, what is left of the year is deducted from your next payments. Before you confirm the change you will see how much you pay and from when. If you subscribed in the app, the change is handled by Apple or Google.
10.7. If you delete your account
If you delete your account while you have Plus subscribed on the website, Calma cancels your subscription at that moment, so that you are not charged again, and the unused part of the period is not refunded (except within the withdrawal period, section 10.8). If you subscribed in the app, Calma cannot cancel it for you: cancel it first in your Apple or Google Play account, or the store will keep charging you. The app reminds you of this before deleting the account.
10.8. Right of withdrawal (14 days)
If you are a consumer and subscribe to Plus on the website, you have the right to withdraw from the contract within 14 calendar days of the day you subscribe, without giving any reason and at no cost.
Calma Plus starts as soon as you pay, and you can use it from that moment. Even so, if you withdraw within those 14 days, we refund everything you paid, without deducting the days you have had it. This is more than the law requires; we do it so that trying Plus is risk-free.
To withdraw, send us a clear statement that you want to withdraw before the 14 days are over, for example using the form in the annex, to soporte@aihacks-es.com, from your account's email address. It is enough to send it before the period ends. We will confirm that we have received it and refund you within 14 days at most of receiving it, using the same payment method you used, at no cost to you. From that moment you go back to the free plan.
The right of withdrawal applies to your first subscription to Plus, not to each automatic renewal: a renewal continues the same contract. If you switch from the monthly to the yearly plan, you have 14 days from that change to withdraw from it, and we refund what you paid for the change.
If you subscribed in the app, withdrawal and refunds are handled by Apple or Google under their terms: on the App Store, at reportaproblem.apple.com; on Google Play, from your order history.
10.9. If a payment fails
If a renewal cannot be charged (for example, because your card has expired), you keep Plus while the payment is retried, for about two weeks: we will let you know by email and in Settings, so that you can update your payment method. If the payment still fails in that time, the subscription is cancelled and you go back to the free plan, without losing your data or owing anything. We will not charge you anything for the delay. To avoid this, we will also email you when your card is about to expire.
10.10. Refunds
Apart from the right of withdrawal and what the law provides, payments are not refunded. If Plus has not worked because of a fault on our side, or you have been charged by mistake, write to us at soporte@aihacks-es.com and we will fix it, refunding what is due.
Legal guarantee. As a consumer you also have the legal guarantee of conformity for digital services: if Plus does not work as described here and in the app, for as long as you have it you can ask us to fix it within a reasonable time and at no cost; if we do not fix it, or the fault is serious, you can ask for a price reduction in proportion to the time it has not worked, or terminate the contract and get back what you paid for the remaining period. Write to soporte@aihacks-es.com.
10.11. If Plus changes or ends
We may change what Plus includes to improve it or to adapt it to technical or legal changes or to the cost of the services it relies on, always at no extra cost to you. If we remove something important from Plus, or stop offering it, we will tell you by email at least 30 days in advance. If the change is to your detriment, you can terminate the contract free of charge within 30 days of receiving the notice (or of the change, if later), and we refund the part of the paid period remaining from that day.
11. Changes to the app
Calma keeps improving: the app may change and we will sometimes ask for your opinion. It is not a service commitment.
12. Availability
We do our best for Calma to work at all times, but there may be outages, due to maintenance or to problems with the services it relies on. At this stage we do not guarantee any specific availability.
13. Liability
We do our best to keep Calma working well, but the free plan comes with no commitment beyond these terms, and with Plus we are responsible for it working as described (section 10.10). To the extent the law allows, we are not liable for indirect damage or for decisions you take based on its suggestions. Nothing here limits your rights under consumer law.
14. Intellectual property
The app, its design, its texts and its code belong to ARTIFICIAL INTELLIGENCE HACKS, SOCIEDAD LIMITADA (AIHacks-ES), and the Calma name and logo are its signs (trade mark applied for at the Spanish Patent and Trademark Office). Using Calma gives you no rights over them. Your data is yours: you give us permission to process it only to provide you with the service.
If you download Calma from the App Store, Apple's standard licence agreement for apps also applies. If you buy Plus on the App Store or Google Play, that store's purchase terms also apply.
15. Changes
If we change these terms in a significant way, we will tell you in the app in advance. If you do not agree, you can delete your account. If you have Plus and a change is to your detriment, you can cancel before it applies and we refund the remaining part of the paid period.
16. Law and courts
These terms are governed by Spanish law. If you are a consumer, you may bring proceedings before the courts of your place of residence.
If you have a complaint, write to soporte@aihacks-es.com or call +34 617 731 325: we will give you a reference number and reply as soon as possible, within one month at most. If you prefer, you can ask us for the official complaint form (hoja de reclamaciones) of the Community of Madrid and we will email it to you. You can also contact the consumer office of your municipality or region. Calma is not a member of any consumer arbitration scheme or other alternative dispute resolution body; if we do not resolve your complaint, you can go to the consumer arbitration board (Junta Arbitral de Consumo) for your area, which will invite us to take part, or to the courts.
