Scheduling tools help companies manage appointments efficiently, but GDPR (also known as DGSVO) compliance adds complexity to the choice. While Calendly offers popular features, its US-based servers create uncertainty for European businesses that need to protect user data. Let's look at what this means for your company and explore secure alternatives that keep your scheduling data protected – we’ll focus specifically on ZEEG, a German scheduling tool that’s GDPR-compliant and helps small businesses and enterprises around the world.
Key GDPR requirements for scheduling software
The implementation of GDPR has fundamentally changed data protection standards. Most businesses don't realize that scheduling tools handle significant amounts of sensitive information - from basic contact details to meeting purposes and attendee preferences. For European companies, protecting this data properly isn't just good practice; it's a legal necessity.
When dealing with GDPR standards, scheduling platforms, like Calendly, must meet specific requirements, and not all of them can do it 100%. Beyond secure data storage, these tools need transparent processes for managing user consent and handling data requests. Additionally, companies must maintain detailed documentation of their data processing activities, which becomes particularly challenging when using tools that store information outside the EU.
First, let's see how Calendly works
Calendly is one of the most popular and well-known online appointment scheduling tools. It allows online appointments and meetings in a simple way via link or embedding on one's website. Calendly queries the desired time slots and allows participants to choose an appointment that suits them.
The advantages of Calendly for appointment scheduling
The pros of using scheduling tools like Calendly are many, as you can see below:
- Easy appointment scheduling via link or widget
- Flexible time windows and buffer times definable
- Automatic confirmation and reminder emails
- Connection to calendar apps like Google Calendar
- There's a Free Calendly version available
Calendly's challenges with regard to data protection and GDPR
Event though there are many benefits in using Calendly, this tool comes with some challenges when it comes to GDPR. Just to name a few:
- Calendly is based in the USA
- GDPR (DSGVO) compliance not guaranteed
- Lack of clarity regarding data storage and access
For companies and users with operations in Europe, the use of Calendly can therefore be associated with the risk of a lack of GDPR compliance. In particular, sensitive personal data may be affected, reasons why you might need to find a reliable alternative.
Zeeg: a GDPR compliant Calendly alternative from Germany
A promising candidate as a GDPR-compliant Calendly alternative from Germany is the tool Zeeg. Zeeg is a scheduling solution made in Germany and meets all requirements of the GDPR. Here are the main advantages of Zeeg:
- Developed in Germany
- Hosted in Europe
- Full GDPR compliance
- Maximum data security through TLS encryption
- Full data sovereignty for users
- Free basic version available
With the EU-U.S. Data Privacy Framework that came into force on July 10, 2023, there is indeed again the possibility to store data of EU users also on U.S. servers. However, this should be treated with caution, as a re-examination by the European Court of Justice (ECJ) is likely. In addition, US companies must meet various requirements to join the agreement. A list of qualified US companies can be found here.
Overall, tools such as Zeeg, which were developed entirely in the EU, continue to offer the greatest possible data security and legal certainty. Companies from Europe should therefore continue to rely on GDPR-compliant providers when choosing scheduling solutions.
How booking works with the Calendly alternative Zeeg
With Zeeg, your German alternative to Calendly, you can easily schedule appointments with customers, team members and partners. With just a few clicks, your calendars sync - whether on Google, Outlook or other platforms. In your Zeeg calendar, you can enter your personal availability for meetings, phone calls or face-to-face conversations and create an individual link to book appointments. Use this link to send your customers, partners or team members an invitation for a digital or face-to-face meeting. They can then enter and book your appointment via the link.
This is how booking an appointment with Zeeg works in just a few steps:
- Enter personal availability in the Zeeg calendar

- Create a custom appointment booking link

- Send link to customers, partners or team members

- These simply book their desired date according to availability

How you can use Calendly alternative to streamline your business
Maximize sales success with clever scheduling
Growing your business means managing more meetings efficiently. Using Zeeg helps sales teams focus on closing deals instead of juggling calendars. The platform's secure, GDPR-compliant design takes care of appointment organization while your team concentrates on revenue growth.
Sales success depends heavily on quick responses and smooth meeting coordination. When potential clients want to talk, making them wait for scheduling details can cost you opportunities. Zeeg's automated systems ensure leads get quick responses and find meeting times that work for everyone.
Teams using Zeeg often see better results because they:
- Connect with more qualified leads through targeted scheduling
- Respond faster to meeting requests
- Spend less time on calendar management
- Focus more energy on actual sales conversations
The real value shows in longer-term results. Sales teams report higher closing rates when they can respond quickly to meeting requests and maintain consistent follow-up. By removing scheduling barriers, representatives spend more time building relationships and less time on administrative tasks.
Take customer service to the next level
Great customer service starts with being available when clients need you. Zeeg helps support teams manage their time while staying accessible to customers. The system routes inquiries to the right team members and keeps everyone informed about upcoming meetings.
By making it easy for customers to book time with your team, you'll build stronger relationships. Quick response times and organized follow-ups show clients you value their time. Plus, when customers can easily schedule support sessions, they're more likely to reach out before small issues become big problems.
Customer service teams particularly benefit from automated reminders and follow-ups. These features ensure no customer falls through the cracks while maintaining professional communication standards. The result is higher satisfaction rates and more loyal customers who know they can count on consistent support.
Optimize your recruitment process with Zeeg
Finding the right talent takes time, but scheduling shouldn't slow you down. Zeeg streamlines the interview process from first contact to final rounds. HR teams can focus on evaluating candidates instead of coordinating calendars.
The platform helps you create a positive experience for candidates by:
- Making interview scheduling simple and professional
- Automating reminders and follow-ups
- Coordinating multiple interviewers efficiently
- Reducing time-to-hire through better organization
When managing multiple candidates across different positions, keeping track of interviews becomes complex. Zeeg's scheduling system helps HR teams maintain clear oversight while ensuring each candidate receives proper attention. This organized approach often leads to faster hiring decisions and better candidate experiences.
How Zeeg optimizes appointment booking
Zeeg is not only the data protection-compliant solution from Germany for online appointment scheduling. This Calendly alternative also offers users various functions to noticeably simplify communication with customers and the organization of internal processes.
- It processes appointment booking and payment easily
Zeeg's integrated payment function makes it particularly easy for service providers and companies to book appointments and pay for their services. Customers book their desired appointment, which is automatically transferred to the provider's Zeeg calendar and synchronized with existing calendars. Payments can also be made directly at the time of booking.
Zeeg also allows buffer times to be set up between appointments so that providers have enough time to prepare for the next meeting. If a booked appointment is canceled, it is automatically released again and available for selection by other customers.
- It automates customer communication effortlessly
Zeeg has intelligent workflow functions that can be used to greatly automate customer communication around appointment booking. For example, automatic reminders and confirmations can be set up via email and SMS to increase attendance at booked meetings.
Personalized messages can also be created for pre- and post-appointment communications that are sent to customers in an automated manner. This provides a consistent and professional experience for customers. Automating recurring tasks also saves internal resources.
- It customizes appointment booking pages to match own branding
A major advantage of Zeeg is the flexible adaptation of the appointment booking pages to the company's own corporate design. This ensures a consistent brand presence across the website right through to appointment booking. The integration of QR codes for even easier access is also possible.
- It simplifies demo booking
The option to easily book demo appointments via their own website is a great advantage for companies. Zeeg, your privacy-compliant Calendly alternative from Germany, optimizes this process with clever automation functions.
Thanks to the integrated iFrame, interested visitors can be automatically assigned to the appropriate contact person for the demo on the website. Zeeg matches team availability in real time so that interested parties can see appointment options at a glance.
Plus, a rotation system also ensures that inquiries are distributed evenly among sales staff. Everyone gets an equal chance to showcase their expertise in demos.
Automated appointment coordination via the website thus increases customer satisfaction and conversion rates. Companies save valuable resources through more efficient processes.
Zeeg provides the intelligent technology to optimize appointment booking and scheduling for demo requests from their own website. Prospective customers thus receive a seamless user experience.
By optimizing appointment scheduling, payment and customer communication with the DSGVO-compliant Calendly alternative Zeeg, customer experience and internal processes can be noticeably improved.
How your Calendly alternative ensures GDPR-compliant scheduling
For companies in the EU, compliance with the GDPR is essential when processing personal data. There are risks here with solutions from the USA such as Calendly. Zeeg, on the other hand, complies with all requirements as a European provider.
When organizing appointments, sensitive information such as contact and payment data is often exchanged. Zeeg stores all data in European data centers in compliance with the GDPR and transmits it end-to-end encrypted. And even if participants from non-EU countries are involved, GDPR compliance is maintained.
Zeeg, on the other hand, provides the guarantee that personal data is only processed on servers in Europe. Also, this promise of high data protection standards can be used effectively for customer acquisition. By actively communicating secure, lawful data processing, providers set themselves apart from the competition.
