We will never sell your data.Not to advertisers, not to data brokers, not to anyone. Ever.
- What you write stays on your device. No account, no email address needed.
- If you sync, it's locked before it leaves. Your phrase is the key, and we never have it, so we can't read your planner. Nobody else can either.
- No ads, no trackers, no analytics. The site loads nothing from other companies, not even its fonts.
- You can delete everything, from your device and our server, in one tap.
In your browser
Everything you write in the planner is saved in this browser. Nothing leaves it unless you turn on sync or ask for a letter by email. No accounts, ads or tracking cookies.
Your notes and patterns
The words you add to a day, like "motivated" or "cranky", are saved with the rest of your planner in your browser. Patterns are worked out on your device too. If you sync, the words are locked with your phrase before they leave, so the server only holds a copy it can't open. They're never added to your Google or Apple calendar link and never put in an email. Nobody at Barkat can read them, and that includes us. The same goes for any pregnancy or breastfeeding you mark: it stays in your planner, and while you're pregnant, cycle notes by email simply pause, without the server being told why.
Your birth chart
Your birth date, time and place are used to draw your chart right here in your browser. Nothing is looked up online and no other company sees them. They're saved on your device, and if you sync, they're locked with your phrase like the rest of your planner. "Forget my birth details" in the chart removes them.
If you sync
Sync uses a six-word phrase instead of an account. Before your planner leaves your device, it's locked with that phrase, so the copy on our server can't be read by us or anyone else without it. The server never keeps the phrase itself.
That also means nobody can reset it. Save the phrase card, save it to your passwords, or add a passkey (Face ID, Touch ID or a fingerprint), and you can always get back in.
The server keeps your last 30 saves, so a mistake can be undone from "earlier copies".
Letters by email
If you ask for a letter to be emailed, the server has to read it to send it. It keeps the letter and your address only until the letter is sent, then deletes both. An address nobody confirms is deleted after a week.
Cycle notes by email
If you ask for cycle notes, Barkat keeps your email address, how often you want them, the goal you picked, and your period start dates with your average cycle length, so it can write each note. Never your notes, symptoms or anything else. They come from letters@barkat.ltd with the plain subject "Your Barkat note". Every note has a stop link, and stopping deletes all of it. Nothing is sent until you confirm from the first email.
Adding your cycle to Google Calendar
What does Google see? Your cycle calendar is the one thing in Barkat that isn't locked, because Google has to read it to show it. Google can see the dates and their names: "✦ new cycle", "✦ green days" and "✦ peak day". If you tick "show my cycle notes too", Google sees those notes as well. Nothing else from your planner goes in. Notes are left out unless you choose them.
What about past periods? Normally the calendar shows only your last three cycle starts and what's coming. If you tick "show my past periods too", every period you've logged goes in as "✦ new cycle", lasting as long as it did. Untick it and they leave the calendar on Google's next check.
Where is it kept? Barkat keeps one copy on its server at a secret link with a long random code in it, so Google can check it for changes a few times a day. Your device writes it there, and only when your dates change. We never sell it or use it for anything else.
Who can open the link? Anyone who has it, so keep it to yourself. Nobody can guess it. If it ever gets out, tap "make a new link": the old one stops working right away, and you add the calendar to Google again.
How do I stop? Tap "stop sharing" in the cycle tab. The link and Barkat's copy are deleted, and the calendar in Google goes empty. To clear it from Google too, remove "Barkat ✦" under Other calendars in Google Calendar's settings.
What if I'd rather Google never see it? Then don't add it. Your cycle works the same in Barkat without it, and there it stays on your device, or locked with your phrase if you sync.
Washi Apps
Washi Deck and Washi Notes (app.washiapps.com) are Barkat's sister apps. Anyone who syncs Barkat and Washi Deck with the same six-word phrase can add Barkat's boxes to their deck: today, cycle, cycle calendar and book. The deck unlocks your planner in your own browser with your phrase, keeps what it shows only while the page is open, and never saves it to the deck or sends it anywhere else. It only reads; it can't change your planner. Nothing is shared between the apps without your phrase. Like Barkat, they load nothing from other companies, count no visits, and never sell your data.
Apple Health
Barkat doesn't send anything to Apple Health. Many people have asked for it, and we're thinking it through for our iPhone app in 2027. If we add it, it will stay off unless you turn it on yourself, and turning it on will take a few deliberate steps. Once your cycle is in Apple Health, Apple's rules and any apps you've allowed to read your Health data apply to it, and Barkat can no longer protect it.
Bringing your history in from Apple Health already works: in the cycle tab, tap "bring in from another app". The file is read on your phone and never uploaded. The same goes for a spreadsheet from another app.
Barkat updates
On barkat.ltd/iphone you can ask to hear when the iPhone app is out. Barkat keeps only your email address and whether you confirmed it, on its own server, and sends nothing until you tap the confirm link. You'll get the launch email and one about Premium before January, nothing more, and every email has a link that deletes your address. Unconfirmed addresses are deleted after a week. We will never sell your email address.
Barkat Premium
Premium is free for everyone through the end of 2026, and anyone who starts using Barkat before then keeps it free for good. This is remembered in your planner, so it follows your phrase if you sync. From January 2027 it will be $9, paid once, never a subscription, and it will carry over to the iPhone app coming in 2027. It's sold through the checkout of Washi Apps, Barkat's sister app. Stripe takes the payment, so we never see your card. Premium follows your six-word phrase: to check whether you have it, Barkat makes a key from your phrase on your device and asks Washi Apps about that key. The phrase itself never leaves your device, and nothing you've written goes with it. We never sell your data.
Deleting
In self, open book, then sync, and choose "delete everything". That erases your synced planner, its earlier copies and its passkeys from the server, and everything in that browser. It can't be undone.
What the site itself does
Every page, script, font and sound comes from barkat.ltd. The site tells your browser not to load anything from anywhere else, not to send where you came from when you follow a link, and not to let other sites show Barkat inside theirs. It never asks for your location, camera or microphone.
