Terms of Use

Last updated: 20 October 2026 · Version 2026-10-20

These Terms of Use govern the subscription to and use of Agento by businesses and professionals. The service is offered exclusively to professionals (B2B). By creating an account and accepting these Terms at sign-up, the Customer enters into a contract with the Provider on the terms below.

1. The Provider

Agento is provided by Spyridon Kaftanis (Σπυρίδων Καυτάνης), a sole proprietor trading as HigherHighLabs (the “Provider”, “we”, “us”).

• Tax ID (ΑΦΜ): 149091546
• Email: skaftanis@gmail.com

2. Definitions

• “Service” or “Agento”: the software-as-a-service (SaaS) platform for appointment booking and business management, including the mobile and web apps, the online booking page, notifications and all related features.
• “Customer”: the business or professional that signs up and subscribes to the Service.
• “Users”: the account owner and the persons (e.g. secretaries, staff) to whom the Customer grants access.
• “End Customers”: the Customer’s own clients who book appointments or are recorded in the Service.
• “Customer Data”: data entered by the Customer or its Users, or collected through the Service on the Customer’s behalf, in particular End Customer data.
• “Subscription”: paid access to the Service under one of the available plans, billed monthly or yearly.

3. Acceptance & professional use (B2B)

1. These Terms are expressly accepted at sign-up. We record the version of the Terms you accepted and the time of acceptance.
2. The Service is intended exclusively for businesses and professionals acting in their professional capacity (e.g. barbershops, hair and beauty salons, gyms and studios, physiotherapists). It is not offered to consumers.
3. Because the Customer is not a consumer, consumer-protection rules, including the right of withdrawal, do not apply. The free trial is provided precisely so that the Customer can evaluate the Service before any charge.
4. The person accepting these Terms confirms that they are of legal age and authorised to bind the business on whose behalf they sign up.

4. The Service

Depending on the plan, Agento offers, among other things: a calendar and appointment management, an online booking page for End Customers, confirmations and reminders by SMS, email and push notifications, customer relationship management (CRM), secretary and staff accounts, statistics, and additional features (e.g. waiting list, session packages, loyalty points, workout programmes, artificial-intelligence features).

The features included in each plan are described on the pricing page. The Service evolves continuously; we may add, improve or change features, without materially reducing the core functionality of your plan during the current billing period.

5. Account & security

• The Customer must provide accurate and complete information (including billing details) and keep it up to date. At sign-up we verify the email address and phone number with a one-time code.
• The Customer is responsible for keeping all Users’ login credentials secure, for the access rights it assigns to them, and for all activity carried out through its account.
• The Customer must notify us immediately of any unauthorised use of, or suspicious access to, its account.
• The Customer is responsible for the accuracy, completeness and lawfulness of Customer Data and of any content it uploads.

6. Free trial

• New Customers get a 10-day free trial. A payment card is required to start, but no charge is made before the trial ends.
• When the trial ends, the Subscription starts automatically on the plan and billing interval (monthly or yearly) you selected and your card is charged, unless you cancel before the trial ends.
• During the trial, up to 5 SMS and 5 emails may be sent to End Customers, and SMS packs cannot be purchased until the first successful payment.
• If you cancel during the trial, the trial ends immediately and you are not charged.
• The trial is offered once per business. We may refuse or end a trial in case of abuse (e.g. repeated sign-ups).

7. Plans, prices & billing

Current prices (excluding 24% VAT) are:

• The Subscription is paid in advance at the start of each billing period and renews automatically until cancelled. Payments are made by card through Stripe; we do not store full card details.
• Emails to End Customers are unlimited (subject to section 10). Free SMS apply to the respective month.
• Additional SMS cost €0.07 per SMS, VAT included, and are bought prepaid in packs (minimum purchase 200 SMS).
• Any one-off services (e.g. building a custom-branded mobile app, a website, SEO), as listed on the pricing page, are agreed and invoiced separately.
• Legal invoices (compliant with the Greek tax authority’s myDATA platform) are issued separately by the Provider. Stripe receipts are payment receipts only, not tax documents. To issue invoices, the Customer provides its company name, tax ID (ΑΦΜ), tax office (ΔΟΥ), address and profession.
• We may change prices with prior notice; a new price applies from the first renewal after the notice, and the Customer may cancel before then.

8. Plan changes & cancellation

• Upgrades take effect immediately, with a prorated charge for the remainder of the current period.
• Downgrades take effect at the end of the period already paid.
• Cancellation can be made at any time from the billing (customer) portal. Access continues until the end of the paid period, after which the account is locked. Cancelling during the trial ends the trial immediately, with no charge.
• Refunds: no refunds are given for billing periods that have already started (monthly or yearly) or for purchased SMS packs, unless these Terms or mandatory law provide otherwise.

9. Failed payments

If a renewal payment fails, the account is locked immediately (the dashboard and online booking are paused) until the payment succeeds. Stripe retries the charge automatically; you can also update your card from the billing portal. If all retries fail, the Subscription is cancelled. Your data is not deleted automatically; you may request its deletion (see section 15).

10. Acceptable use

The Customer and its Users must not use the Service:

• to send unsolicited messages (spam) or messages to recipients for whom there is no lawful basis. The Customer is responsible for having a lawful basis and, where required (e.g. for promotional messages), the consent of End Customers for the SMS, emails and push notifications it sends;
• for content that is unlawful, offensive, misleading or infringes third-party rights (e.g. intellectual-property or data-protection rights);
• to attempt to circumvent or breach security, gain unauthorised access to others’ data, reverse engineer, scrape, or overload the Service;
• to resell or make the Service available to third parties without our written agreement.

The SMS sender name is set by the Service. We may apply usage limits to protect the Service and may suspend or terminate an account in case of abuse or breach of this section.

11. Data processing on behalf of the Customer (Article 28 GDPR)

11.1 Roles

For Customer Data, in particular End Customer data (e.g. names, phone numbers, emails, appointments, history, notes, packages and points), the Customer is the controller and the Provider is the processor within the meaning of Regulation (EU) 2016/679 (GDPR). This section constitutes the data processing agreement under Article 28 GDPR. For the account data of the Customer and its Users, the Provider acts as controller, as described in the Privacy Policy.

11.2 Subject matter, duration and nature

• Subject matter and purpose: providing the Service (bookings, calendar, notifications, CRM, statistics and the other features the Customer enables).
• Duration: for the term of the contract and until the data is deleted or returned under section 11.5.
• Nature: storage, organisation, retrieval, sending of messages and other operations required to run the Service.
• Categories of data subjects: End Customers and, where applicable, the Customer’s staff.
• Categories of data: identity and contact details, appointments and history, notes and other information the Customer chooses to record. The Customer must not record special categories of data (e.g. health data) beyond what is strictly necessary and only where it has a lawful basis.

11.3 Provider obligations

• The Provider processes Customer Data only on the Customer’s documented instructions (these Terms and the Customer’s settings and actions in the Service) and only to provide the Service, unless processing is required by EU or Greek law. It does not use Customer Data for its own purposes and does not sell it.
• It ensures that persons with access to the data are bound by confidentiality.
• It implements appropriate technical and organisational security measures (Article 32 GDPR), such as encryption in transit and at rest, role-based access control and database security rules.
• It assists the Customer, as far as possible, in responding to data-subject requests (access, rectification, erasure, etc.) and in complying with Articles 32 to 36 GDPR.
• It notifies the Customer without undue delay after becoming aware of a personal data breach affecting Customer Data, with the information available.
• It makes available to the Customer, on request, the information necessary to demonstrate compliance and contributes to audits at a reasonable time and in a reasonable manner, with due protection of confidentiality and of the security of the Service.

11.4 Sub-processors

The Customer gives general authorisation for the sub-processors below. Each of them is bound by data-protection obligations equivalent to these. We will give notice of any addition or replacement of sub-processors by updating this page or by email; the Customer may object on reasonable grounds and, if no solution is found, terminate the contract.

When an End Customer chooses to sign in with a Google or Apple account, those providers act as identity providers for that sign-in. Transfers outside the EEA are covered by the EU-US Data Privacy Framework, where applicable, and/or by the European Commission’s Standard Contractual Clauses.

11.5 Return and deletion

The Customer may at any time, and in particular when the contract ends, request the export and/or deletion of Customer Data. Following a deletion request, the data is deleted within a reasonable time, unless retention is required by law. Backups are deleted in their normal rotation cycle.

11.6 Customer obligations

The Customer warrants that it has a lawful basis for processing End Customer data and for sending messages to them, that it provides them with the required information (Articles 13-14 GDPR), and that its instructions to the Provider are lawful. End Customers address their requests to the Customer; if we receive such a request directly, we will forward it to the Customer.

12. Intellectual property

The software, design, trademarks and content of the Service belong to the Provider or its licensors. The Customer receives a non-exclusive, non-transferable right to use the Service for the duration of the Subscription. Customer Data and the Customer’s content (e.g. logo, photos, texts) remain the Customer’s property; the Customer grants us a licence to use them only to the extent necessary to provide the Service (e.g. displaying them on the booking page or in its app). We may freely use suggestions and feedback for improvements.

13. Availability & support

The Service is provided “as is” and “as available”. We make reasonable efforts to ensure high availability but do not guarantee uninterrupted or error-free operation. There may be interruptions for scheduled maintenance or upgrades, which we aim to carry out at low-traffic times. Delivery of SMS, emails and push notifications also depends on third parties (mobile carriers, email providers, operating systems) and cannot be guaranteed. Support is provided by email.

14. Limitation of liability

1. To the maximum extent permitted by law, the Provider is not liable for indirect or consequential damages, loss of profit, loss of revenue, goodwill or reputation, or loss of data that could have been avoided by reasonable measures on the Customer’s part.
2. The Provider’s total liability for all claims arising from the contract is limited to the amount paid by the Customer for the Service in the 12 months preceding the event giving rise to the claim.
3. The above limitations do not apply where the law does not permit limitation of liability, in particular in cases of intent or gross negligence.
4. The Customer is responsible for the data and content it records, for the messages it sends through the Service and for its own legal compliance, and indemnifies the Provider against third-party claims arising from a breach of these Terms by the Customer or its Users.

15. Term, suspension & termination

• The contract applies from acceptance of these Terms for as long as the account is maintained. The Customer may cancel the Subscription at any time as set out in section 8.
• We may suspend access immediately in case of non-payment, abuse, risk to the security of the Service or third parties, or serious breach of these Terms, and may terminate the contract if the breach is not remedied or is serious.
• We may also permanently discontinue the Service with at least 30 days’ notice; in that case the pro-rata portion of prepaid fees for the unused period is refunded.
• When the Subscription ends, the account is locked. Data is not deleted automatically, so that the Customer can reactivate its account; the Customer may request export or deletion at any time (section 11.5). Accounts that remain locked and inactive for more than 12 months may be deleted after at least 30 days' notice by email.
• Provisions that by their nature should survive termination (e.g. amounts owed, limitation of liability, data processing until deletion, governing law) continue to apply.

16. Changes to these Terms

We may amend these Terms, for example because of changes to the Service or the law. We will notify you in advance by email or in the app, stating the effective date. Continued use after the effective date constitutes acceptance of the new Terms. For material changes, you may be asked to accept the Terms again in the app. If you do not agree, you may cancel your Subscription before the effective date. The date and version of the Terms in force are shown at the top of this page.

17. Governing law & jurisdiction

These Terms are governed by Greek law. The courts competent for the area of Epidavros, Greece, have exclusive jurisdiction over any dispute arising from them, after a good-faith attempt at amicable resolution.

18. Miscellaneous

• These Terms, together with the Privacy Policy and the pricing page, constitute the entire agreement regarding the Service, unless otherwise agreed in writing.
• If any provision is held invalid, the remaining provisions continue to apply. Failure to exercise a right does not constitute a waiver of it.
• The Customer may not assign the contract without our consent. The Provider may assign it to a successor of its business, with notice to the Customer.
• Notices to the Customer are sent to the account email address or through the app.
• These Terms are available in Greek and English. In case of any discrepancy, the Greek text prevails.
