Yongdu helps individuals track ownership costs, including depreciation, valuations, financing estimates, and cost analysis. The website calculator is a simplified example; the hero displays an actual app screenshot.
Estimates
Results depend on your inputs, chosen models, and available exchange rates. They support personal records, review, and decisions, and are not investment, credit, tax, legal, or other professional advice. Actual repayments follow contracts and lender rules; resale proceeds depend on the actual transaction.
Data and backups
Check your inputs, keep regular backups, and secure devices and files. Full backup import replaces local records and disables sync; enabling it again merges cloud assets. Individual deletions sync, conflicts need a version choice, and sync is not a backup. Disabling sync or Pro expiry retains existing data. Services, connectivity, and account status affect sync; background real-time updates are not promised.
See the Privacy Policy for data practices and Support for help.
License and transactions
Apps obtained through the App Store are subject to Apple’s Standard EULA or the applicable custom agreement provided at acquisition. This page explains product use and does not replace the applicable App Store license terms.
Yongdu Pro offers monthly and annual auto-renewing subscriptions and a one-time lifetime purchase, all with the same Pro features. Prices, currencies, and billing periods are confirmed by the App Store. Subscriptions renew unless canceled at least 24 hours before the current period ends; canceled access continues through the paid period. Lifetime access does not automatically cancel an existing subscription. Expiry pauses advanced analysis and sync while retaining records and free features. Apple handles refunds; refunds or revocations may end Pro access. This website does not take payments.
Responsible use and rights
Do not use the app unlawfully, infringe others’ rights, or disrupt its operation. Use must comply with applicable law and licenses. Nothing here excludes or limits non-excludable consumer rights under applicable law.
