What Browser-Based Privacy Really Means
A page can run in your browser and still send everything you type to a server. So browser-based is not a privacy guarantee. You have to look at what the application actually does with the data.
Local processing means the work stays on the device
A tool can read a list, create pairs, generate teams, or choose a result entirely in JavaScript running on your device. No backend is required for that calculation.
Pikyo is built this way for the working data used by its tools. Names, questions, lists, pairings, and generated results do not need to be sent to Technway for the tools to work.
Local storage is still visible on that browser profile
Saved lists and preferences can live in localStorage. That is different from cloud storage because the data stays with the browser profile, but it does not make the data invisible to other people using the same profile.
On a shared computer, saving a participant list may be a bad idea even if the website never uploads it. Clear site data when the information should not remain on the device.
Some actions genuinely need a server
A contact form is different from a random picker. Your message and email address have to leave the browser if they are going to reach Technway.
Server infrastructure can also create technical logs such as request times, IP addresses, user agents, or error information. A privacy description should be clear about those different data paths instead of saying everything stays local.
Analytics should not need your actual list
Product analytics can answer questions such as which tool was opened or whether a result was copied without collecting the names, custom entries, questions, or generated personal results.
That distinction matters. Useful analytics should measure the product without turning user content into analytics data.
A few habits make a big difference
Use names only when names are actually needed. Avoid adding medical, legal, financial, or confidential notes to a general selection tool. On shared devices, review what you saved and clear it when you are done.
- Know which actions stay local
- Avoid entering data the tool does not need
- Remember that local storage remains on the device
- Clear saved data on shared browsers
- Review optional analytics choices when privacy matters to you
Treat this as practical guidance, not a replacement for legal, professional, or safety requirements where they apply.
