So easy you will actually keep it up
Most logging apps get abandoned because of long forms. Day1Keeper is "journal first, details later".
🔔
Gentle reminders
One summary a day at a time you choose, only on days something needs looking after. One-off or repeating, as many as you need. No red badges, no guilt.
📖
A timeline of everything
Photos, notes, costs and events in order — for each thing, for your whole life, and a "My Year" recap.
💰
Spending summary
Weekly, monthly or yearly — by module, type and where it went. Currencies are kept separate, never mixed.
🧾
AI receipt scanning
Snap a receipt and AI fills in the amount, date and shop. You always check before saving (never used for health data).
📁
All your documents
Warranties, deeds, policies, lab reports — linked to what they belong to, with reminders before they expire.
12 modules for every part of life
Turn on only what you need and put them in your own order.

Your data is yours
We only describe what the system actually does.
To be clear: data is encrypted in transit (HTTPS) and at rest by our providers, but this app is not end-to-end encrypted.
- Only you and the people you choose can see it — enforced in the database and tested so other users cannot.
- Photos and documents are private, opened through temporary links that expire within an hour.
- Download all your data at any time, free forever.
- Health stays off until you consent, is never sent to AI, and can be deleted without deleting your account.
- No selling data, no ads, no training AI on your data.

Questions
Is it free?
Yes. The free plan holds 3,000 photos, and notes, events and expenses are unlimited. If paid plans for more space come later, downloading your own data stays free forever.
Do I need the App Store or Play Store?
No. Day1Keeper is a web app: open app.day1keeper.com and tap "Add to Home Screen" (iPhone, Safari) or "Install app" (Android, Chrome) and it works like any other app.
Does it work offline?
You can view what was loaded before and log events to send later (except health data and entries with an amount, which need a connection).
How do reminders work?
Once a day at a time you choose (8 AM by default), only when something needs looking after — like "3 things to look after today". On iPhone, add the app to your home screen first. Health reminders never show names on the lock screen.
Can my family help look after things?
Yes. Invite people to view or help log, item by item. They only see what you share.
Does AI see my data?
Only when you tap "Scan receipt" and agree. It uses a paid service that does not train on your data, and it is never used for health data.
Is Day1Keeper related to Daykeeper?
No, they are different, unrelated apps. Day1Keeper has the number 1 in its name, as in "Day 1". Our only website is day1keeper.com and the app lives at app.day1keeper.com.
Does it diagnose or give investment advice?
No. Day1Keeper records what you and your doctor wrote down. It does not interpret results or give any advice or trading signals.
