TzolK'in
Maya Sincronario · Privacy & Support
TzolK'in reads the day's kin — its galactic signature — from the Maya Sincronario and Dreamspell count, and lets you decode any date. It is a calculator and an almanac. It runs entirely on your device.
Last updated: July 22, 2026
TzolK'in collects nothing and sends nothing. It has no account, no sign-in, no analytics, and no servers. Everything it computes and everything you enter stays on your phone. We — the developer — never see any of it.
Everything the app remembers is kept in your device's own local storage. None of it leaves the device.
If you turn on the daily "your kin this morning" reminder, the app schedules those notifications on your device using the system's local notification service. Nothing is sent to or through a server. You can turn them off in the app's settings or in your system settings at any time.
When you share a kin card, the app builds a PDF on your device and hands it to your system's standard share sheet. What happens next — which app or contact you send it to — is entirely your choice and is handled by your operating system, not by TzolK'in.
TzolK'in is suitable for all ages and collects no personal data from anyone, including children.
If this policy ever changes, the updated version will be posted on this page with a new "last updated" date. Because the app collects nothing, we do not expect material changes.
Questions, a bug, or an idea? We read every message.
There are two long-standing differences. First, the correlation: TzolK'in uses GMT 584283, the count kept by the National Museum of the American Indian and by living Guatemalan day-keepers. Some academic sources use 584285, which differs by two days. Second, the day-boundary rule: some lineages count a birth before dawn as the previous day. TzolK'in lets you choose (midnight, sunrise or sunset) in the person editor, and shows both kins when you are near the boundary.
TzolK'in keeps them deliberately separate and always labelled. The Dreamspell layer is José Argüelles' 1987 system — tones, seals, the oracle, wavespells, and a leap-day rule. The authentic K'iche' layer is the traditional continuous count (Cholq'ij), Haab and Long Count. They are never mixed.
Open the app once first — the widget shows a placeholder until the app has filled in the day. Then long-press your home screen, tap +, and search for TzolK'in. On iOS, lock-screen widgets are added from Settings → Wallpaper → Customize.
TzolK'in is bilingual — English and Spanish. It follows your device's language automatically, and you can switch it by hand in Settings.
Delete any person from the people list, or delete the app to remove everything at once. Nothing is stored anywhere but your device.
