Why are no available slots showing on the booking page?

Usually a service, staff member, schedule or advance booking rule is missing.

Updated 26 May 2026

Check four things: the service is active, at least one staff member can perform it, weekly hours have open ranges and the day is not marked as a holiday or closed.

Also review minimum notice, maximum booking days and slot interval in Bookings.

Cookie Policy

Last updated: 10/05/2026

This policy explains which cookies and similar technologies https://citas.bkmodules.com uses and how you can manage them, in accordance with Regulation (EU) 2016/679 (GDPR) and applicable e-Privacy legislation.

1. What are cookies?

A cookie is a small file or identifier that a website stores on your device when you visit it. They allow the site to function, keep your session active, remember preferences, and measure service usage.

2. Categories we use

Necessary (technical): essential for security, session management, CSRF protection, language, forms, and consent management. They cannot be disabled; without them the service does not function properly.
Preferences: remember non-essential settings such as color theme or language.
Analytics: measure visits and aggregate usage to improve the service (Google Analytics 4, only if enabled by the business).
Marketing: measure campaign performance or display personalized content (Google Tag Manager, only if enabled by the business).

Non-essential cookies are not loaded until the user accepts them through the consent panel.

3. Embedded content (maps and videos)

To avoid degrading the user experience, this site may display embedded maps and videos using privacy-oriented variants: Google Maps Embed API and OpenStreetMap/Leaflet for maps, and youtube-nocookie.com for videos. These integrations do not set advertising cookies until the user interacts with the content. The provider may receive technical data (IP, user agent) necessary to deliver the content. This loading relies on the legitimate interest of displaying requested content and, for certified US providers, on the EU-US Data Privacy Framework.

4. Consent management

You can accept, reject, or customize cookie categories from the banner displayed on your first visit, and modify your choice at any time using the "Cookie settings" link in the footer. Your choice is stored in your own browser and, in aggregate and non-personal form, in our compliance records.

5. Third-party cookies

When a customer business enables optional tools on its landing page (analytics, marketing, videos), the corresponding providers may set their own cookies according to their respective policies: Google, Meta, YouTube, etc. BK Modules LLC does not control those cookies.

6. More information

For questions about cookie usage or to exercise your rights, contact us at bkmodules@bkmodules.com.

Terms of Service

Last updated: 10/05/2026

These Terms of Service ("Terms") constitute a legally binding agreement between you ("User" or "Customer") and BK Modules LLC, a limited liability company organized under the laws of the State of New Mexico (United States), owner of the BKCitas service available at https://citas.bkmodules.com ("the Service"). By accessing or using the Service, you fully and unconditionally accept these Terms. If you do not agree, you must not use the Service.

1. Subject matter

BKCitas is a software-as-a-service (SaaS) platform that enables professionals and small businesses to manage bookings, customers, communications, and payments online. These Terms govern all relationships between BK Modules LLC and the User from the moment of registration or first access.

2. Registration and account

To access the management panel you must register an account with truthful, accurate, current, and complete information, and keep it updated at all times. You are solely responsible for the confidentiality of your credentials and for any activity carried out under your account. Registration and use of the Service is restricted to individuals over 18 years of age and to legal entities acting through representatives with sufficient legal authority. BK Modules LLC may request identity verification or proof of authority to contract at any time.

3. Plans, subscription, and billing

BKCitas offers subscription plans whose features and pricing are detailed at https://citas.bkmodules.com. The subscription begins upon registration and plan selection, with charges processed automatically and periodically (monthly or annually) through the payment provider Stripe. Unless applicable law in your country of residence expressly grants a right of withdrawal, amounts already billed are non-refundable. You may cancel your subscription at any time from the panel; the Service remains active until the end of the current billing period. BK Modules LLC reserves the right to modify prices with a minimum of thirty (30) days' notice via email or the panel; continued use constitutes acceptance of the new prices.

4. Acceptable use and prohibited conduct

You agree to use the Service solely for lawful purposes consistent with these Terms. Without limitation, the following are expressly prohibited:

Engaging in illegal activities or activities that infringe third-party rights.
Attempting to access systems, accounts, or data without authorization.
Reverse engineering, decompiling, disassembling, or extracting the source code of the software.
Conducting mass scraping, automated crawling, or using bots without prior written authorization.
Sending spam, malware, ransomware, phishing, or any malicious or unlawful content.
Impersonating BK Modules LLC, its employees, or any third party.
Reselling, sublicensing, or transferring access to the Service without prior written authorization from BK Modules LLC.
Interfering with the functioning, security, or availability of the Service.
Harvesting contact data without consent.

Violations may result in immediate account suspension or termination, without prejudice to any civil and/or criminal legal actions BK Modules LLC deems appropriate.

5. Intellectual property and brand protection

BK Modules LLC owns or is licensed to use all intellectual and industrial property rights in BKCitas, including, without limitation: source code, software, platform architecture, visual design, algorithms, trademarks, logos, trade names, texts, images, and iconography.

The name "BKCitas", the associated logo, and all derivatives are protected trademarks and the exclusive property of BK Modules LLC. Their use, reproduction, imitation, dilution, registration, or exploitation — in any form or jurisdiction — without prior written authorization is expressly prohibited. Infringement will result in civil and criminal claims to the fullest extent permitted by law.

Subscribing to the Service grants the User only a limited, personal, non-exclusive, non-transferable, and revocable license to use the Service during the subscription period. No ownership rights in the software or any component of the Service are transferred. Any feedback, suggestions, or improvements you provide regarding the Service may be used by BK Modules LLC without restriction or additional compensation.

6. End-customer data and sub-processing

In the context of booking and communication management activities carried out through the Service, BK Modules LLC acts as a data processor with respect to end-customer data managed by the User, with the User being the data controller under the GDPR and applicable law. The User warrants that they have the appropriate legal basis to process their customers' data, have provided legally required notices, and that their use of BKCitas is compatible with data subjects' rights. BK Modules LLC will process such data only per the User's documented instructions and will delete or return it upon contract termination as agreed.

7. Service availability and disclaimer of warranties

BKCitas makes reasonable efforts to keep the Service available on an uninterrupted basis, but does not guarantee continuous, error-free, or uninterrupted availability. Outages may occur due to maintenance, updates, or force majeure.

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, whether express or implied, including, without limitation, implied warranties of merchantability, fitness for a particular purpose, and non-infringement. To the extent applicable law does not permit complete exclusion of these warranties, such exclusion applies to the maximum extent permitted.

8. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, BK Modules LLC SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING, WITHOUT LIMITATION, LOSS OF PROFITS, DATA, REPUTATION, OR GOODWILL, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

BK Modules LLC's total cumulative liability to the User, for any cause, shall not exceed the total amount actually paid by the User during the twelve (12) months preceding the event giving rise to the claim, or one hundred US dollars (USD 100) if no payment was made during that period. Some jurisdictions do not allow the limitation or exclusion of certain liabilities; in such cases, these limitations apply to the maximum extent permitted by law.

9. User indemnification

You agree to indemnify, defend, and hold harmless BK Modules LLC and its officers, employees, agents, and partners from and against any claims, liabilities, damages, losses, costs, or expenses (including reasonable attorneys' fees) arising from: (a) your use of the Service in breach of these Terms; (b) violation of third-party rights; (c) unlawful processing of end-customer data; or (d) any content or operation performed under your account.

10. Term, suspension, and termination

These Terms take effect upon registration and remain in force for the duration of the subscription. Either party may terminate the agreement by canceling the account. BK Modules LLC may suspend or cancel access immediately in the event of a material breach of these Terms, fraudulent use, or illegal activities, without prejudice to any claims for damages. Upon termination, BK Modules LLC may delete account data no sooner than thirty (30) days after termination, except where retention is required by law.

11. Modifications to these Terms

BK Modules LLC may modify these Terms at any time. Material changes will be notified via email or a panel notice with a minimum of fifteen (15) days' prior notice. Continued use of the Service after that period constitutes acceptance of the revised Terms. If you do not accept the changes, you must cancel your subscription before they take effect.

12. Governing law and dispute resolution

These Terms are governed by and construed in accordance with the laws of the State of New Mexico and applicable United States federal law, without regard to conflict-of-law principles, and without prejudice to mandatory consumer protection provisions of the User's country of residence. The parties agree to attempt to resolve any dispute amicably within thirty (30) days of written notice. Failing agreement, disputes shall be submitted to the courts of Albuquerque, New Mexico (USA), unless mandatory law in the User-consumer's country of residence establishes different jurisdiction. If any provision is found invalid, the remaining provisions shall remain in full force. Failure to exercise any right shall not constitute a waiver. These Terms constitute the entire agreement between the parties on the subject matter hereof.
