Backup, Sync, and Exports

Complete ZIP Backup Format

Unlike basic cataloging utilities that export only text logs and discard photos, Horologe produces a self-contained, compressed .zip archive:

Backup_Horologe_2026-10-18.zip
├── manifest.json            ← Full database dump (watches, services, wrist time, accuracy)
└── watch_images/            ← High-resolution photo collection
    ├── watch_1_cover.jpg
    ├── watch_1_image_1.jpg
    └── ...

This archive format is 100% interoperable between iOS and Android: an archive generated on iPhone restores cleanly on Android, and vice versa.

iCloud Synchronization (iOS Exclusive)

On Apple devices, Horologe incorporates advanced CloudKit sync architecture:

• Relational Data: synchronized in the private primary-v2 record.
• Deduplicated Photos: each image is stored as a file-<sha256> record. If an image already exists on iCloud, redundant re-uploading is skipped.
• Throttling Resistance: during large initial sync batches, withServerRetry respects CKErrorRetryAfterKey to prevent HTTP 429 rate limit errors.

PDF Spec Sheets and CSV Exports

• A4 Watch Spec Sheet: export a polished PDF document displaying the watch’s hero photo, technical specifications, service history, and estimated valuation for insurance or consignment.
• CSV Data Dump: export tabular data to open your collection in Excel, Numbers, or Google Sheets.
