Terms of service
Last updated: 20 September 2026
These terms govern the use of Reserv (reserv.day). They are written in plain language and deliberately without fine print: if something strikes you as unfair, tell [email protected] and we will discuss it.
1. Who provides the service
The service is provided by the operator of reserv.day, referred to below as "we". The contact channel for any contractual matter — notices, complaints or cancellations — is [email protected].
"You" or "the Customer" is the individual or company that opens an account. Reserv is aimed at professionals and businesses acting in the course of their trade, not at consumers.
By creating an account you accept these terms and the Privacy policy. If you accept them on behalf of a company, you confirm you have authority to bind it.
2. What Reserv is
A web application for managing appointments. It includes a public booking page on your own address within reserv.day, a calendar, service and opening-hours management, client records with history, automatic email confirmations and reminders, a QR code for your premises, and optional sync with Google Calendar and Outlook.
We are not an intermediary or a marketplace: we do not find clients for you, we take no commission per booking, and we do not come between you and your client. Your relationship with your clients is entirely yours.
We do not process your clients' payments. Charging for the service you provide is handled by you, outside Reserv.
3. Account, eligibility and security
To open an account you must be an adult and be registered as self-employed or as a company, or be acting on behalf of one.
The details you give us must be true and current. An email address you do not read is a problem for both of us: important notices go there.
You are responsible for your credentials and for everything done with your account. If you suspect unauthorised access, email [email protected] immediately and we will terminate the session.
One account corresponds to one business. You may give your team access, but you are answerable for what they do.
4. Acceptable use
You may not use Reserv for unlawful activity, nor for sexual services, sale of illegal substances, usurious lending, or any activity requiring an official authorisation you do not hold.
You may not send unsolicited commercial communications through our email system. Appointment reminders are exactly that: reminders of an appointment the client asked for.
You may not attempt to access other businesses' data, probe the platform's security without prior written permission, resell the service as if it were your own, or extract data in bulk by automated means.
You may not upload content that infringes third-party rights, or use another business's name or logo.
If you find a security flaw, tell us at [email protected] before making it public. We respond, we are grateful, and we do not pursue people who report in good faith.
5. Your obligations regarding your clients' data
This article is short, but it is the one we most want you to read.
For your clients' data, you are the controller, not us. You decide what the booking form asks for, what it is used for and how long it is kept. We only process it on your behalf.
Accordingly, you warrant that: you have a valid legal basis for processing the data you enter or collect; you inform your clients who you are and how you handle their data, through your own privacy policy; you handle the rights requests addressed to you; and you obtain consent where needed, including parental authorisation for children under 14.
If you enable the DNI/NIE field, the burden of justifying it is yours. It is a national identifier and should only be collected where there is a concrete reason: identifying a patient in a clinical record, issuing a named invoice, or an equivalent legal obligation. If you cannot explain why you are asking, do not ask. It is off by default.
Do not use the notes field for clinical or health information unless you have an Article 9 GDPR basis for processing it and have assessed the risk. Reserv is not certified as a clinical records system.
You will hold us harmless against third-party claims and penalties arising from a breach of the above. This clause does not apply where the breach is ours.
6. 14-day free trial
Every new account starts with 14 days of full access, no card required and no automatic charge at the end. There is no catch: if you do nothing, you are charged nothing.
What happens on day 15 if you have not subscribed:
Your account stays alive and you can sign in. You can see your appointments, clients, services and history, and export all of it.
Your public booking page stops accepting new bookings. Bookings already confirmed remain in your calendar and their reminders still go out as normal.
The moment you subscribe, everything switches back on instantly with nothing lost.
If you do not subscribe, we keep your data for 90 days in case you come back, then delete it.
Only one free trial per business.
7. Pricing, subscription and VAT
One plan, Plan Pro, with everything included: unlimited bookings and services, reminders, calendar sync, QR code and client history.
Price: €9.99 per month, or €99 per year (equivalent to two months free).
VAT: displayed prices include Spanish VAT at 21%. Nothing is added at checkout — you pay exactly the price shown. If you are a business established in another EU member state with a valid intra-Community VAT number, contact us before subscribing and we will invoice you under the reverse charge.
How you are charged: through Stripe, using the card or payment method you register. We neither see nor store your full card number.
Price changes: we will email you at least 30 days in advance. The new price applies from your next renewal, never within a period already paid for. If you are not happy with it, you can cancel before it takes effect and you will not be charged.
Failed payments: if a charge fails, we retry and tell you. If it is still unpaid after 14 days, the account moves to the same state as at the end of the trial: you can still sign in and export, but the booking page stops accepting new bookings. We do not close the account or delete anything over a failed payment.
8. Automatic renewal and cancellation
The subscription renews automatically, monthly or annually depending on the plan, until you cancel. We say so plainly here because that is exactly what happens.
You can cancel whenever you like, from your dashboard, in the subscription section, without calling anyone, writing an email or explaining why. The next renewal date is always visible on that same screen.
When it takes effect: at the end of the period you have already paid for. If you cancel on the 3rd of a month that runs to the 30th, you keep full service until the 30th. No further periods are charged.
There is no minimum term, no cancellation penalty, and no hidden one-year tacit renewal clause anywhere.
Cancelling does not delete your data. Your account moves to the read-only state described above, and you can export everything or reactivate whenever you want.
9. Refund policy: 14 days, no questions
If within 14 days of a charge you are not satisfied, we refund that charge in full. We do not ask why.
It applies equally to the monthly and annual plans, and to both the first payment and any renewal. Email [email protected] with the word "refund" from your account address, within 14 calendar days of the charge.
We process the refund within 14 calendar days of your request, to the same payment method you used. We charge no fee for refunding.
When you request a refund the subscription is cancelled and the account moves to the read-only state. You can keep exporting your data.
This is a commercial guarantee we give voluntarily. Signing up as a professional or a company, you are not entitled by law to the 14-day right of withdrawal that consumers get — and we give it to you anyway, because it is the right way to sell software and because we would rather refund ten euros than argue about them.
One reasonable limit: one refund per business per year. If someone subscribes and asks for their money back every month, we will conclude the product is not for them and gently suggest they stop buying it.
10. Service availability
We work to keep Reserv available at all times, but today we do not offer a contractual availability commitment or an SLA with penalties. We would rather tell you before you find out than promise a 99.9% we cannot back. When an SLA exists, it will be published here and we will let you know.
There may be interruptions for maintenance — which we will try to schedule outside Spanish business hours and announce in advance — for failures at our infrastructure providers, or for reasons of force majeure.
We may modify, add or withdraw features. If we withdraw a significant feature you are using, we will give you 30 days' notice and you may cancel with a pro-rata refund of the unused portion.
A practical and honest recommendation: export your data now and then. The export is in the dashboard and takes seconds.
11. Intellectual property
The software, design, the Reserv trade mark and the documentation are ours or our licensors'. We grant you a non-exclusive, non-transferable, revocable right of use, limited to the term of your subscription and to the purpose of using the service.
You may not copy, decompile or create derivative works from the software, except where the law expressly allows it.
What you upload stays yours: your logo, your text, your client data and your appointment history. You grant us only the technical licence strictly needed to host it, display it on your booking page and back it up. That licence ends when your data does.
We will not use your trading name or logo as a commercial reference without asking you first.
12. Processing of personal data (Article 28 GDPR)
This article is the data processing agreement required by Article 28(3) GDPR. It forms part of these terms and is accepted with them: there is no separate document to sign. If your advisers need a standalone signed document, email [email protected] and we will send one with the same content.
In this article, "Controller" means you and "Processor" means us.
a) Subject matter and duration
The Processor processes personal data on behalf of the Controller for the sole purpose of providing the Reserv service described in these terms. The processing lasts as long as the account does, plus the deletion periods set out under "On termination".
b) Nature and purpose of processing
Hosting, storage, retrieval, modification, structuring and deletion of the data needed to manage bookings and clients, and sending appointment confirmations and reminders on the Controller's behalf.
c) Categories of personal data
Identification and contact data (name, email, phone), the Spanish national ID (DNI/NIE) where the Controller enables that field, appointment data (service, staff member, date, time, price, status) and free-text notes entered by the Controller or the data subject.
d) Categories of data subjects
The Controller's end clients and, where applicable, the Controller's staff with access to the account.
e) Acting on documented instructions
The Processor will process the data only on the Controller's documented instructions, which are these terms and the options the Controller configures in the dashboard. If Union or Member State law requires the Processor to process data otherwise, it will inform the Controller before doing so, unless that law prohibits it. The Processor will tell the Controller if, in its opinion, an instruction infringes data protection law.
f) No use for own purposes
The Processor will not use the Controller's clients' data for its own purposes, will not disclose it to third parties other than as set out in this article, will not use it to train artificial intelligence models, and will not use it for advertising.
g) Confidentiality
The Processor ensures that persons authorised to process the data have committed themselves in writing to confidentiality, or are under an equivalent statutory obligation, and that the commitment survives the end of the relationship.
h) Security (Article 32)
The Processor applies appropriate technical and organisational measures: encryption in transit and at rest, logical row-level isolation between customers enforced by the database engine, least-privilege access control, logging of staff access, daily backups retained for 30 days, and periodic restore testing. The measures in force are described in the Privacy policy.
i) Sub-processors
The Controller gives the Processor general written authorisation to engage sub-processors. The current list is in the Privacy policy. The Processor imposes on each sub-processor, by contract, the same obligations it assumes under this article, and remains fully liable to the Controller for their performance. Any addition or replacement will be notified at least 30 days in advance; during that period the Controller may object on reasonable grounds and, if no solution is found, terminate the subscription with a refund of the unused portion.
j) International transfers
Data is hosted in the European Union. Transfers outside the EEA are limited to the sub-processors identified as such in the Privacy policy and rely on the Standard Contractual Clauses in Implementing Decision (EU) 2021/914 and, where applicable, the EU-US Data Privacy Framework.
k) Assistance with data subject rights
The Processor will assist the Controller, through the dashboard's own functions (view, edit, export and delete) and, where those are insufficient, with direct support within 5 working days, in responding to requests for access, rectification, erasure, restriction, portability and objection. If a data subject contacts the Processor directly, it will refer them to the Controller and notify the Controller without delay.
l) Assistance with Articles 32 to 36
The Processor will reasonably assist the Controller with security of processing, breach notification, communication to data subjects, and data protection impact assessments and prior consultations, taking into account the nature of the processing and the information available.
m) Breach notification
The Processor will notify the Controller of any security breach affecting its data without undue delay and in any case within 48 hours of becoming aware of it, with the information available on the nature of the incident, the categories and approximate number of data subjects and records affected, the likely consequences and the measures taken. Notification to the supervisory authority is the Controller's responsibility.
n) On termination: return and deletion
When the service ends, the Controller has 30 days to export its data from the dashboard in a structured, commonly used format. 60 days after closure the Processor will delete all data from live systems; backups still containing it will rotate out within a further 30 days at most. Anything a law requires to be retained is excepted, and will be blocked and unused for the statutory period.
o) Information and audit
The Processor will make available to the Controller the information needed to demonstrate compliance with this article and will allow for audits, including inspections, conducted by the Controller or an auditor it mandates. Audits require 30 days' notice, are limited to one per year absent a security incident, take place during business hours, and must not affect other customers' information. The Processor's reasonable costs are borne by the Controller unless the audit reveals a material breach.
p) Records of processing
The Processor maintains the record of categories of processing carried out on behalf of the Controller required by Article 30(2) GDPR, and provides it on request.
13. Limitation of liability
We are liable for direct damage we cause by breaching these terms. Our total aggregate liability to you, on any ground and in any twelve-month period, is limited to the greater of: the amount you have paid us in those twelve months, or one hundred euros.
We are not liable for loss of profit, loss of custom, loss of opportunity, or indirect or consequential damage.
Nor are we liable for the consequences of a reminder not arriving: email depends on third parties and on spam folders. An automatic reminder reduces no-shows, it does not eliminate them, and it is no substitute for your own judgement with important clients.
Nothing in this article excludes or limits our liability for wilful misconduct, gross negligence, fraud, personal injury, or anything else Spanish law does not permit us to exclude. If a court finds a limit excessive, it will be reduced to the maximum permissible and the rest of the article remains in force.
14. Suspension and termination
You can close your account whenever you want, from the dashboard.
We may suspend or close an account if the acceptable use article is breached, if the activity puts the security or operation of the service at risk for others, or if an authority orders us to.
Unless the seriousness of the matter or a legal order requires immediate action, we will warn you first and give you 14 days to put it right. If we suspend for a breach by you, there is no refund of the current period; if we close for our own reasons with no breach by you, we refund the unused pro-rata portion.
We may also stop providing the service altogether. In that case we will give 90 days' notice, charge no renewal after the notice, refund the unused pro-rata portion, and keep data export working until the last day.
15. Your data on termination
Your data is yours and you can take it with you. Export is always available in the dashboard, in CSV, at no cost, with no limit on how often, and without having to ask us.
After closing the account you have 30 days to download it. 60 days after closure we delete everything from live systems, and backups finish rotating within a further 30 days at most.
We will never hold your data hostage to keep you paying.
16. Changes to these terms
We may amend these terms. Material changes are announced by email and with an in-app notice at least 30 days in advance, and take effect at your next renewal.
If a change does not suit you, you can cancel before it takes effect and we will refund the unused pro-rata portion. Continuing to use the service after the effective date means accepting them.
Typographical corrections and changes required by law may apply immediately; we will announce those too.
17. Governing law and jurisdiction
These terms are governed by Spanish law.
For any dispute, the parties submit to the Spanish courts, unless a mandatory rule assigns jurisdiction elsewhere.
Before going to court, email [email protected]. It is faster for both of us.
If any clause of these terms is held void, the rest remains valid and the void clause will be replaced by a valid one of equivalent effect.
