Who we are
Yiorti is run by Nom de Plume Analytique Inc., a New York corporation. Contact: info@yiorti.com.
Using Yiorti
Yiorti shows nameday dates for several Orthodox church calendars and helps you remember your contacts' namedays. It's free to use. We work hard to get every date right, but calendars and local customs differ. Dates marked "?" aren't double-checked yet, and you should confirm anything important with your parish.
Your contacts
If you load a contacts file, it is read on your own device and is never uploaded to us. See our privacy page.
Buying from us
Prices are shown in US dollars and include any taxes we're required to collect unless stated. Payments are handled by Stripe; we never see your card number. When you order, you agree to these terms and to our refunds and shipping policy.
Founding supporter
A one-time payment. When the Yiorti app launches, every paid feature is yours for life, on any of your devices, signed in with the same account, and your name (if you wish) goes on our founders page. Founder purchases are processed by Stripe's Link, which is the seller of record and handles sales tax and VAT. If the app hasn't launched by the date we show at checkout, you can ask for a full refund.
Nameday dedications
You choose the name, the day and a short message. We show it on that day's page after we check it. We may decline messages that are hurtful, commercial or not about a person's nameday or memory, and refund you in full.
Sponsors
Sponsors appear in one marked "Sponsor" space. We don't track visitors for sponsors. Sponsor agreements are made separately in writing.
Changes
We may update these terms; the date above shows the latest version.
Law
These terms are governed by the laws of the State of New York, USA.
