## What is 九零事件?

NinEvent is a local-first timeline app built around the things that matter to you. Create an event for anything that happens repeatedly or deserves to be remembered, then add updates, notes, photos, tags, and numbers as you go. See how each event changes over time.

Ways to record
- Quick entry: Capture the moment in a sentence.
- Option entry: Mark a status with custom labels.
- Number entry: Track weight, spending, counts, and more.
- Option + number: Combine both for a more complete update.
- Add photos, automatically compressed and saved.
- Organize events by category, then filter and search by tag, year, or keyword.

Time-based insights
- Automatically see event counts, average intervals, and tag breakdowns.
- Turn on Predictions for recurring events to estimate when they’ll happen next.
- Review yearly counts and intervals.
- Track countdowns and birthdays from your first entry, with your age or time remaining displayed.
- Time spans adapt between hours, days, weeks, months, and years.

Layout and appearance
- Choose a single-column layout, a two-column layout, or a photo gallery for your home screen.
- Use dark mode, light mode, or follow your system setting.
- Choose from multiple fonts and adjust text size.

Your data, your device
- By default, all data stays on your device. Core features work offline.
- Entries and photos are stored locally. Secret keys are never displayed again after entry.
- Protect the app with a passcode and automatic locking when you leave (Pro).
- Export and import JSON data, and back up or restore photos in a ZIP file.

Cloud sync (Pro)
- Sync with S3-compatible storage, including Tencent Cloud COS, Alibaba Cloud OSS, AWS S3, Cloudflare R2, and MinIO.
- Incremental sync across devices, with retries when your connection returns.
- Data syncs directly from your device to your object storage, without a relay service.

NinEvent Pro
One-time purchase, yours forever:
- Create unlimited events (free tier: 3)
- Sync data with S3 cloud storage
- Lock the app with a passcode
- Remove the built-in guide event
- Get future feature upgrades

After purchase, restore it in the app using Restore Purchases.
