THE BOMB AT THE FINAL: “SEXWORKERS SHOULD USE THE TOOL!” What initially sounds like an ordinary tech service for classified ad users and landlords turns out to be a small revolution for the Swiss erotic industry: ContactGuard - a new platform from the Basel area - wants to protect privacy with a cipher service for WhatsApp. And the makers say it openly: sex workers in particular should be able to use the tool to protect their number and work more professionally.
“We want to consciously take countermeasures,” explains the team behind Geissmann Webconsulting from Birsfelden, which has been active in the adult business for over 15 years and already runs an established web design agency for the erotic industry, ero-page.ch. "The no-adult policy of many providers or absurdly high prices are no longer appropriate. We believe that anyone who works independently - regardless of whether they are an escort, dominatrix or call boy - has a right to secure, professional communication."
HOW DOES THE SERVICE WORK? THE CIPHRE CODE AS A NUMBER BODYGUARD The principle is brilliantly simple:
User registers on contactguard.ch with his WhatsApp number. A personal cipher is generated in the dashboard (e.g. “SONNE123”). This cipher plus the ContactGuard service number (also in Swiss mobile format) is posted in personal ads, websites or eBay classifieds. Interested parties write the ContactGuard number - with the cipher code at the beginning of the message. ContactGuard's AI checks the message for spam, fraud or trolling. Serious inquiries are forwarded anonymously - the user only sees the interested party's contact information in the WhatsApp chat. The user decides whether he wants to reply with his real number - or not.

This is what it looks like: Messages are filtered and forwarded anonymously.
The dashboard transparently shows which messages got through and which were blocked. Users can add numbers to the block list themselves. And the most important thing: the WhatsApp number always remains secret.
AI POWER AGAINST SCAMMERS AND SPAM – “AT THE LIMIT OF WHAT’S POSSIBLE” ContactGuard relies on GPT-4o for message analysis. The AI recognizes:
Spam messages (“hey send a picture pls !!!1”) Fraud attempts (“FREE iPhone – click here now!!!”) Trolling and dubious requests “We are at the limit of what is possible when it comes to message-based detection,” say the creators. "Of course, we can't 100% rule out the possibility that a regular message also has malicious intentions - that might come with v2.0. But all common scamming approaches are reliably detected and eliminated."
In addition, ContactGuard operates its own fraud report database for the Swiss mobile network - numbers of known fraudsters automatically end up on the block list.
THE GAME CHANGER FOR SEXWORKERS: AUTOMATED AI ANSWERS This is where things get really exciting: In higher price plans, the AI can not only filter, but also automatically respond to standard queries.
Example: A customer asks: "When are you free?" or “How much does an hour cost?”
ContactGuard’s AI can respond directly – instructed in advance by the user: "I'm available Monday to Friday from 2 p.m. to 10 p.m. One hour costs CHF 300. You can find more information on my website: ..."
“Answering the same questions 30 times every day is a task that should not be underestimated,” explain the developers. “Self-employed people without office staff in particular can save a lot of time here.” The conversations can be tracked at any time - transparency in all directions is the credo.
Important: Personal contact is not a substitute. The AI only handles recurring information requests.
SWISS PRIVACY POLICY – HOSTED IN SWITZERLAND In times of data scandals and darknet leaks (see the recent Pornhub hack), data protection is a sensitive issue - especially for sex workers.
ContactGuard promises:
Hosting in a renowned Swiss data center Data is only processed anonymously Compliant with the new Swiss Data Protection Act (nDSG) Only available for the CH mobile network “Data protection is particularly important to us,” says the team. "We do not pass on any data to third parties - except to verified processors listed in our data protection declaration."

Trial version (free) 5 redirects included To test and try out Individual plans From CHF 4.– for 4 days (1 CHF/day) Longer terms = cheaper daily prices Business Adult Services CHF 100/month (adult sector) CHF 80.–/month (standard) Up to 10 ciphers and 10 forwarding numbers For agencies, studios, clubs Tailored commercial solutions A competent sales team is available for individual enterprise solutions – non-binding and discreet.
“We also have to keep an eye on misuse of the service,” emphasize the creators. "And of course the service is not free for us either. But we want to remain fair - and we also accept Schoggiweggli as payment." 😉
BETA START IN APRIL – LIVE FROM MAY 2026 ContactGuard has been online since the beginning of April 2026 – still in beta mode. “But this should only last for a short time,” says Geissmann Webconsulting. “We want to go live from May.”
The first testimonials from the industry are now to be collected. Anyone who is interested can test the service for free at contactguard.ch.
WHY SEX WORKERS? The question is obvious: Why does a tech startup specifically address this target group?
“This has to do with our experience,” explains the team. "We started gaining experience with our first erotic platform over 15 years ago. It's a very regulated market if you want to be on safe legal ground. And it's still very common to have a no-adult policy - or to charge absurdly high prices."
And then the crucial sentence: “We think this “good-bourgeois” treatment is no longer up-to-date and we want to consciously take countermeasures.”
Is this a PR coup or a real social issue? “Every reader should answer this for themselves,” said the creators.
EXPERT OPINION: “DATA PROTECTION IN SEXWORK IS IMPORTANT FOR SURVIVAL” The research shows: WhatsApp privacy is a long-running topic. Meta recently introduced new protection functions with “Advanced Chat Privacy” (source: Heise), but the telephone number remains a sensitive point.
A leaked number can have dramatic consequences, especially for sex workers:
Stalking and harassment Doxxing (publication of private data) Blackmail and sextortion Loss of privacy in everyday life "In an industry where digital censorship on Instagram and TikTok is systematically increasing while demand for discrete services is booming, a tool like ContactGuard is more than just practical - it can be a livelihood," comments an industry insider.
COMPETITION? FAILURE! The research shows: There is currently no comparable service for WhatsApp ciphers with AI spam protection specifically for the adult industry in Switzerland. Classic cipher services such as newspaper advertisements are outdated and not digitally integrated. Virtual number services do not offer AI protection or industry expertise.
ContactGuard occupies a niche – and could become the standard.
CONCLUSION: MORE THAN JUST A TECH TOOL – A QUESTION OF ATTITUDE ContactGuard is more than a clever app idea. It's a statement: "Sex workers have a right to safe, professional communication - without stigma, without absurd prices, without a no-adult policy."
It remains to be seen whether the concept will work. The fact is: the need is there. The technology works. And the team behind Geissmann Webconsulting has over 15 years of industry experience.
