Frequently Asked Questions

How does Prefero work?

Prefero presents you with dilemmas between immediate and gradual returns. You can choose an option, let a timer expire (which triggers a coin flip), or manually flip a coin. Each decision is recorded, analyzed, and can be cryptographically verified.

What is cryptographic verification?

Every decision generates a unique SHA-256 hash based on the quandary ID, your selection, and timestamp. This creates a tamper-proof proof document that you can share, proving your decision was made at a specific time.

Is my data private?

Yes! All data is stored locally on your device. We don't collect, transmit, or store any of your data on external servers. Your decision history, statistics, and custom dilemmas remain completely private.

What are the in-app purchases?

Prefero is free to download and use. You can purchase credits ($0.99 for 3 credits) to create custom dilemmas, or subscribe to Advanced Proof features ($2.99/month or $9.99/year) for NLP analysis and detailed insights.

Can I create my own dilemmas?

Yes! With premium credits, you can create unlimited custom dilemmas. Each dilemma costs one credit, and credits never expire. You can organize your custom dilemmas by category and use them in the decision flow.

What devices are compatible?

Prefero works on iPhone and iPad running iOS 17.0 or later. The app is optimized for all screen sizes and supports both portrait and landscape orientations.

How do subscriptions work?

Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current period. You can manage and cancel subscriptions in your Apple ID Account Settings. Subscriptions provide access to Advanced Proof features with NLP analysis.

Can I export my decision history?

Currently, you can share individual proof documents, but bulk export of history is not available. All data remains on your device for privacy. This feature may be added in future updates.
