No account, because there are no KashCal servers​

This isn't a privacy setting you switch on. It's the shape of the app. There is no KashCal account to create, no KashCal server anywhere for your events to pass through, and no analytics, telemetry, or ad SDK riding along inside. There is, quite literally, nowhere for us to send your data, so there is nothing for us to collect. A privacy policy is easy to write when the honest version is "we don't have your data and never did."

Your calendar lives on your phone​

Your events sit in a secure database on your device that other apps can't read. The only things that ever leave your phone go to servers you chose: your events sync to your own calendar server, iCloud, Nextcloud, Fastmail, or any CalDAV service, and an RSVP goes to the organizer who invited you. Nothing else goes anywhere.

And when you're offline, none of that matters. KashCal is offline-first: everything you do lands instantly on the device, and it quietly catches up with your servers when there's a connection. A plane, a basement, a dead zone, the calendar still works.

Passwords that can't be lifted from a backup​

When you connect a calendar server, its password is encrypted on your device with AES-256, and the key lives in the Android Keystore, hardware-backed where the phone supports it. The key is tied to that one device, so a stolen backup can't be replayed onto another phone to reach your accounts. The trade-off is honest: move to a new phone and you re-enter your passwords. We think that's the right side of the line.

Permissions you can actually reason about​

KashCal asks only for what a feature in front of you needs, and it asks in context, with a plain reason. Contacts is for suggesting guests and showing birthdays. Calendar access is for showing the calendars other apps already keep on your phone. Decline any of it and the rest of the app keeps working. No all-or-nothing gate at the door.

Free, and open about it​

KashCal is free and open source under Apache-2.0, so "we don't track you" isn't a promise you have to take on faith. The source is right there to read. If we ever added a tracker, someone would see the commit.

Your calendar was never anyone else's business. Now it's built that way.

Type a #tag, get a chip​

Add a tag in the event form, or fling a #dentist straight into Quick Add and watch it land as a colored chip. That chip then follows the event around the day, week, and agenda views like it owns the place. Tap the event open and the tags are right there in quick view, quietly confirming that yes, this is a #focus block, and no, it is not the third #standup of the day you had every right to skip.

Start typing and KashCal hands back the tags you already use, ranked by how often you reach for them. It is the only known cure for "Errands" quietly fracturing into "errands," "ERRANDS," and one deeply confident "Errnads" by Thursday.

And if you decide tags belong above your notes rather than below, the row's little ⋮ menu will move it, and we will pretend that was our idea all along.

The honest fine print​

Tags currently work on the events KashCal syncs itself: your iCloud and other CalDAV calendars. The device's own calendars, the Google, Samsung, and Exchange ones Android politely shoves through the door, are still tag-free for a release or two while we teach them manners. Rather than let your tags quietly vanish into the void, we simply hide the tag row on those events for now.

This is version one of roughly several. More tags, more places, more tricks are queued up.

While we had the tweezers out​

A few papercuts, gone:

• Events with no length, the ones you pin to a single moment, used to disappear entirely in the day and week views. They now show up as the small blocks they always meant to be, and no longer draw on top of each other when they overlap.
• Emoji in a synced description arrive as the emoji you sent, instead of a puzzled little box.
• A garbled duration from some other app can no longer bend an event's end time back to before it started.

Everything in this release​

• Event tags: colored chips on events, shown in the day, week, and agenda views and in the event quick view, on iCloud and CalDAV events for now
• Create tags from the event form with usage-ranked suggestions and inline # autocomplete in the title
• Add tags from Quick Add by typing #tag, persisting across create and all edit scopes
• Reorder the form tag row above or below notes from its ⋮ menu
• Tidied the event-form layout, and moved the location field up under the title
• Fixed zero-length and very short events vanishing or overlapping in the day, 3-day, and week views
• Fixed emoji and other extended characters in synced descriptions rendering as a stray box or wrong character
• Fixed a malformed event duration producing an end time before the start
• Fixed self-hosted CalDAV/ICS sync hanging on "Preparing to sync" over LAN or VPN networks

Small labels, better plumbing, fewer papercuts. Tag it and move on.

The agenda knows what month it is​

The top of the agenda now shows the month you're actually looking at, and keeps pace as you scroll, so August rolls into September without you wondering where the summer went. It's the same month header the week and month views use, now doing an honest day's work over here too.

And there's more of it to scroll: ninety days ahead instead of thirty, because your future has a way of arriving whether we render it or not. A full quarter, in one list, no swiping to the next screen to find out what October is holding.

A timeline that remembers​

The day, 3-day, and week timelines have been persuaded to stop having amnesia. Pinch to zoom the hours in or out to the density you like, and it now stays exactly where you left it after you close the app, rather than resetting to the default overnight and pretending the two of you never met.

It restores the zoom and the scroll position together, so you reopen at the same time of day, at the same size. This is per-device UI comfort, so it isn't dragged along in your settings backup, it just makes the phone in your hand feel like the one you were using yesterday.

Back from 1969​

The month and full-month views had a charming habit of opening in December 1969 if you arrived from the agenda without tapping a day first. Lovely for nostalgia, useless for dentist appointments. It now opens in the current month, having been gently reminded which decade we are all living in.

Everything in this release​

• Agenda now shows the next 90 days of events instead of 30
• The agenda top bar shows the current month and updates as you scroll, replacing the static "Agenda" title
• The day, 3-day, and week timelines remember your pinch-to-zoom hour height across app restart
• Fixed the month and full-month views opening on December 1969 when no day was selected yet

No confetti this release, just a calendar that stops tripping over its own feet. Sweating the small stuff is our whole personality.

Want the flashy bits instead? Take the KashCal Challenge: find the one thing your old calendar can't do, tag #KashCal, and dare a friend to match it.

Your color, everywhere​

So this release we got out of the way. Pick your accent from all 92 colors, and it runs through the entire app and, for the first time, out onto your home screen widgets too. The agenda, week, month, and date widgets all wear it, down to a proper raised add button. You'll find it under Settings, then Appearance.

Prefer the old magic where the color follows your wallpaper? Automatic keeps your Material You colors exactly as they were. Nothing changes unless you want it to.

Every color is contrast-checked as it lands, so whatever you pick, the text on top of it stays readable, in light mode and dark.

Calendar You​

Our marketing team, several donuts deep by mid-afternoon, has decided to call this Calendar You. We did the math on 92 colors, one calendar, and infinite you, and we could not find the flaw, so it is approved. Please clap.

Two smaller kindnesses​

While we were in a generous mood, the week and 3-day views learned to stay put. Reopen the app and you land back where you were looking, not scrolled off to some default hour like nothing happened.

And moving an event to another calendar no longer quietly eats a title or note you edited in the same breath. What you typed is what you keep.

Everything in this release​

• Accent color picker: theme the whole app and all home screen widgets with any of 92 colors, defaulting to KashCal Teal
• Automatic accent keeps your Material You and wallpaper colors
• Agenda, week, month, and date widgets recolor to your accent, with a raised add button
• Week and 3-day views restore your last scroll position across app restart
• Moving an event to another calendar preserves title and note edits made in the same save

Ninety-two colors. Still one calendar. Now unmistakably yours.

Pick your colors​

KashCal now has a proper theme picker. Stay on System, pin Light or Dark, or switch on KashCal Teal, our own palette that follows your phone's light and dark setting while keeping the brand green front and center. It runs through the whole app, contrast-checked so text stays readable on every surface, light or dark. You'll find it under Settings, then Appearance.

Wear your support​

The second choice is the icon on your home screen. If you've chipped in to keep KashCal free and ad-free (or you'd like to), you can now wear it: a gold Supporter icon with a little heart on the calendar card. Pick it under Settings, then App Icon, in whichever flavor you like. Keep the KashCal name, or go incognito with the same icon labeled simply "Calendar."

Whether you're already a supporter or about to become one, here's a thank you from us.

Everything in this release​

• New theme picker in Settings: System, Light, Dark, or KashCal Teal
• KashCal Teal palette follows your phone's light and dark setting and is applied app-wide, with contrast checked for readability
• New supporter app icon: a gold card with a heart, chosen under Settings, then App Icon
• Two supporter variants, sharing one icon: one keeps the "KashCal" name, one shows a discreet "Calendar" name on the home screen

KashCal, the calendar you already love, now in your colors and wearing your badge.

Supporting open source has always felt good. Now it looks good too, right there on your home screen. Not a supporter yet? Join in. It's quicker than your coffee order.

With TalkBack on, you can now move through KashCal by ear. Jump between headings, hear sync and offline status the moment it changes, and get told when a sign-in or a save fails instead of wondering why nothing happened. Events announce what they are, so a cancelled event says "cancelled" out loud rather than just looking faintly sad about it (it wears a line through it now, for the sighted crowd too). Bottom sheets say their name as they open, the drawer tells you which view you're in, and a subscription can finally be deleted with a real action instead of a swipe nobody could find.

While we were teaching it manners, we sent the languages out to live where they belong. KashCal now advertises all 67 of them to Android, so on Android 13 and up you pick the app's language in system settings alongside everything else, instead of spelunking through ours.

Two smaller dignities came along for the ride. Rotating your phone in the middle of an event no longer throws the whole thing away, and typing a title now capitalizes the first letter like a grown-up.

Same calendar. Now it works with the screen off, the phone sideways, and your eyes shut.

Everything in this release​

• Full screen-reader (TalkBack) support: headings, spoken status, event state read aloud
• Cancelled events are now crossed off (#276)
• Set KashCal's language from Android system settings (Android 13+, 67 languages)
• Delete a subscription with an accessibility action, not just a swipe
• Rotating the device no longer discards the event you're editing (#286)
• Event titles auto-capitalize the first letter (#285)

KashCal is free and open source. Get it on F-Droid or read the docs.

We keep meaning to invent something important. Then July 22 rolls around, the annual Pi Approximation Day party starts (the one where 22/7 gets to cosplay as π and nobody files a complaint), someone gets ideas, and we end up improving the calendar again. Here is what escaped this time.

Exact minutes, finally​

The 5-minute time wheel is lovely right up until you need "3:47," at which point it just shrugs. So there is now a keyboard button on the time picker: tap it, type any minute you please.

Events already sitting on an odd minute show the exact time as tappable text instead of quietly rounding themselves to the nearest five while you looked away. Your 8:52 standup stays 8:52.

A lighter download​

In honor of 22/7 being a wonderfully compact stand-in for something infinite, we went hunting for fat to trim and found the app hauling a crate of packing peanuts. We cleaned house. KashCal is now roughly a third smaller to download and install. Same calendar, less luggage.

Everything in this release​

• Type an exact minute. A keyboard button on the time picker lets you enter any minute instead of snapping to the nearest five. Odd-minute events now show their real time as tappable text.
• Roughly a third smaller. Trimmed redundant packaging so the download and install footprint shrink, with no change to what the app does.

Still just a calendar. Now a slightly better one. Happy (approximately) Pi Day.

KashCal is free and open source. Get it on F-Droid or read the docs.

It is also the app that is wide open when you hand your unlocked phone to a friend to "just look at the photo."

KashCal now has App lock. Turn it on, and opening the app throws up a curtain.

KashCal

Locked

Unlock

Flip it on in Settings and your next open is a lock screen, not your week. Unlock with fingerprint, face, or your PIN. No new password to invent, no "please create a 6 digit KashCal code." Your phone already knows how to check it is you. We just ask it to.

It is one more way KashCal stays private by default: no account, no trackers, and now a lock on the door. Here is how App lock works.

Your calendar. Your eyes only.

The list​

• A new event from Quick Settings. Drop a KashCal tile next to your flashlight and Wi-Fi toggles. Pull down from the top of the screen, tap it, and you're typing a new event, even over whatever app you were in. The fastest way to catch a plan before it slips.
• Plain-language events. Type "Yoga every Tuesday 7am at the studio" and it becomes a real recurring event, with the time, the place, the repeat, and the title each landing where they belong.
• Share an event as a card. One tap turns any event into a designed card and a tap-to-add file, sent together in any chat. Your friend taps once to drop it on their own calendar. No screenshots to retype, no invite that drags in extra apps.
• Real CalDAV, out of the box. Nextcloud, Radicale, Fastmail, Baikal, Zoho, SOGo, Stalwart, and more, syncing two ways with no middleware app, no relay server, and no second thing to install. Your phone's Google and Outlook calendars ride along too.
• iCloud on Android. Sign in once and your iCloud calendars sync both ways, shared family calendars included. No bridge, no export-import dance.
• Time insights, on-device. Busiest day, meeting-free days, weekend load, your next free block. It works the numbers out on your phone, no work account and no cloud crunching your schedule.
• Six views, your way. Month, agenda, three-day, week, month-full, and year. Pinch to zoom, drag to reschedule, and color any event from a curated palette or the full color wheel.
• Private and free. No KashCal account, ever. No ads, no trackers, no analytics. Credentials are encrypted with the Android Keystore, and the whole thing works offline from first install. Free and open source under Apache-2.0.

None of the above is a trial, a teaser, or a "pro" tier. It's the whole app. Found the one thing your old calendar couldn't do? That's your challenge entry.

Take the challenge​

1. Get it, then brag. Install KashCal and find the thing your old calendar couldn't do.
2. Post it. A screenshot or one line, anywhere you hang out, tagged #KashCal.
3. Dare a friend. "Mine can do this. Can yours?" Then pass it on.

Lines to steal​

Pick the one that's true for you, copy it, and post it wherever you already hang out: Reddit, Mastodon, X, Lemmy, a group chat. Tag it #KashCal and dare a friend to match it.

My calendar opens a new event from the Quick Settings panel, before I've even left the app I'm in. Can yours? #KashCal

I type "dinner with mom friday 7pm" and my calendar just makes the event. No form. Free, open source, no account. #KashCal

Finally syncing my iPhone family calendar on Android with no middleman. #KashCal

Found an Android calendar with real CalDAV out of the box, on-device time insights, and a 92-color wheel. No ads, no trackers, no paywall. #KashCal

92 colors, each with a real name. Yes, "peru" is a color. We were as surprised as you.
