Terms of Use

Service

Synka Life is an iOS and Android app that estimates future cash flow and asset trends from the conditions you enter. The website provides legal and support information; it does not offer a web version of the planning service.

Simulation results

Results are projections based on entered conditions and calculation assumptions. They do not guarantee future income, spending, assets, interest rates, inflation, taxes, social insurance, pensions, education costs, or housing costs. The current model is for Japan. Foreign-currency conversion is for display reference and does not reflect another country's systems or living costs.

The app does not provide individual advice about financial products, investments, insurance, mortgages, taxes, law, inheritance, pensions, or education funding. Check official information and consult a professional when making important decisions.

Free, temporary ad unlocks, and Pro

Free includes the basic diagnosis. If you choose and complete a rewarded ad, some detailed views, FIRE mode, or backup creation may be available within the applicable feature and session scope. A different screen or base plan may require a separate ad.

Rewarded ads do not unlock Pro editing, higher save limits, comparison of up to five plans, or PDF, image, and CSV exports. Pro provides ad-free details, eligible editing, and expanded save, comparison, and export features. The features available are those shown in the app.

Pro purchases and restores

Pro is a one-time product offered in the app. Purchases and restores use the App Store on iOS and Google Play on Android; RevenueCat is used to check access. Price, purchase terms, and refunds follow the purchase screen and the applicable store terms. Use the in-app restore feature after a purchase.

Ads and external links

Rewarded ads appear when you explicitly choose to view one. The ad SDK may handle device and ad delivery information. PR and affiliate links are identified under the advertising policy and take you to external sites. We do not guarantee an external service's content, prices, eligibility review, contract, or results.

Storage and backups

Plans are stored on your device. You can create a backup and keep it in a location you choose. Restore reads a backup file that you select. Keep a backup when you need to protect against device failure or data deletion.

Prohibited conduct

You must not break the law, access or alter the service improperly, make excessive requests, impersonate another person, infringe rights, misuse ads, payments, or access rights, or interfere with the service.

Liability and changes

To the extent permitted by law, the operator does not guarantee the accuracy, completeness, continuity, or fitness for a particular purpose of the service, and is not liable for losses arising from use or unavailability of the service. This does not exclude liability that cannot be limited by law.

We may change these terms as needed and will announce important changes in the app or on the website. Established: May 11, 2026. Contact: [email protected]
