Thanks for asking. While there is no perfect way for any creator to assure their users that their service is 100% secure, I will try my best to answer your concern..

No, this tool does not save any personal data.

The only thing that the web app collects is analytics data (page visits, clicks) via Google Analytics and PostHog. Since contact number is not appended to URL before redirecting, analytics wouldn't collect number with url.So no personally identifiable, private data is shared or saved.

How do you assure your user that you don't save contacts?

Again, I wish there was a way I could give full assurance that I don't collect private data. Except for checking the web app security by yourself, every time before entering the contact number, you will have to take my word on this and trust me.

As a step towards being open, I have open-sourced code on github.

But then, the code deployed on the website can be something else. You will either have to trust this web app (or any website on the internet for this matter) or build yourself from scratch.

At last, I can hire a cybersecurity agency to audit the website, but then you will have to trust the agency :D

WhatsApp has an unpopular way to open chat conversation with unsaved contact number - wa.me link.

You can create a special wa.me link (https://wa.me/COUNTRYCODE+PHONE) and open it in browser.

WhatsApp Anyone use the same mechanism, but while offering you added convenience! It's simple, secure & installable website.
