About Tohar

A WhatsApp reminder service for keeping the laws of family purity.

How it started

Tohar was built by a young couple. In our first year of marriage we kept a paper calendar and marked the waiting days, the hefsek and the seven clean days by hand. Nothing reminded us, and every cycle we counted again.

One of us has been a software developer for some years. That became a tool that works out the days by your minhag and reminds you of each bedika on time, inside WhatsApp, with no extra app on the phone.

What is checked before release

• The halachic texts Tohar sends were checked before launch. A summary of the halachot is on the Hebrew site.
• The hefsek, seven clean days and mikvah night calculations are tested automatically across hundreds of scenarios: Ashkenazi and Sephardi minhag, four or five waiting days, sightings before and after sunset.
• Tohar sends nothing on Shabbat or Yom Tov. A reminder that falls on Shabbat moves to after Shabbat, once the stars are out.
• Tohar helps you remember and count. It does not replace asking a rav; any doubt goes to a rav or a yoetzet halacha.

What Tohar is not

• Not a medical service. It does not diagnose, treat or give medical advice.
• Not a shop. Nothing is sold, and there are no payments through WhatsApp.
• Never the first to write. A conversation starts only when you send "Hello". You confirm at sign-up that you want reminders, and you can write "stop" at any time.
• Not yet for outside Israel. Times, sunset and Shabbat follow Israel time.
