DayjoyPrivacy policy
Last updated 13 November 2026
Dayjoy is made by Michael Ofosu ("we", "us"). This policy covers the Dayjoy app, this website and buying Dayjoy. In short: your tasks and notes stay on your computer, the app has no account and no tracking, and buying Dayjoy shares only what a sale needs.
The app
Everything you put into Dayjoy (tasks, notes, routines, focus time and settings) is stored in a database on your computer. We never receive it. The app has no account, no analytics, no crash reporting and no advertising.
Dayjoy only goes online for things you set up:
- Calendars. If you add a calendar address, Dayjoy fetches it from that address every 15 minutes. Your calendar provider sees those requests, as it would from any calendar app.
- Sync. If you choose a sync folder, Dayjoy writes a file there. Whichever service syncs that folder (Dropbox, iCloud Drive, OneDrive, Syncthing or another) handles it under its own terms.
- Buying. The Buy button opens the checkout in your web browser.
Backups and the Markdown copy of each day are written to folders on your computer. The dayjoy command and its MCP server run on your computer only. An AI assistant you connect to them sees what it asks for, under that assistant's own terms.
Your licence key holds a licence number, the product and the date it was issued. It doesn't contain your name or email address, and Dayjoy checks it on your computer without contacting us.
Buying Dayjoy
Dayjoy is sold through Polar, which acts as reseller and merchant of record: Polar takes the payment, charges sales tax or VAT, and sends your receipt. At checkout you give Polar your email address, your payment details and your billing country, plus an address where tax rules need one. Polar's privacy policy covers how Polar uses them.
We see your order in Polar: your name and email address, your country, what you bought and when. We never see your full card details.
After you pay, Polar sends you to our thank-you page, which runs on Cloudflare. It asks Polar for your order so it can show your licence key, and keeps nothing afterwards. Like any web host, Cloudflare may log requests (such as IP addresses) for a short time to keep its network secure. If we email you your key, the email is sent through Resend and contains your key and order number.
This website
This website sets no cookies and has no analytics or tracking, and its fonts come from this site rather than a font service. The company that hosts it may keep standard server logs (such as IP addresses and the pages requested) for a short time, for security.
When you write to support@dayjoy.pro, we use what you send to answer you, and delete the conversation once it's no longer needed, usually within a year.
Why we use your information
- To sell you Dayjoy and give you your key (to perform our contract with you).
- To answer your questions, and to prevent fraud such as stolen cards or shared keys (our legitimate interest in running Dayjoy).
- To keep the sales records tax law requires (a legal obligation, which Polar meets as merchant of record).
We don't sell your information, use it for advertising, or share it with anyone except the services named on this page, which handle it on our behalf.
How long we keep it
Order records stay in Polar for as long as tax and accounting rules require. Support emails are deleted once they're no longer needed. The thank-you page keeps nothing.
Your rights
You can ask for a copy of the personal information we hold about you, or ask us to correct or delete it, by writing to support@dayjoy.pro. Depending on where you live (for example the EU, the UK or California), you may have further rights, such as objecting to how we use your information or complaining to your data protection authority. We answer within 30 days.
Some of the services named here are based in the United States. Where your information leaves your country, they use the safeguards the law requires, such as the EU's standard contractual clauses.
Children
Dayjoy isn't meant for children under 16, and we don't knowingly collect their information.
Changes
When this policy changes, the new version appears here with a new date. If a change affects you, we say so on this website before it takes effect.
