About this app

🦊 CONTRACTS, COSTS AND DEADLINES AT A GLANCE

Fristenfuchs helps you manage contracts and subscriptions and calculates an estimated cancellation date from the details you enter — for mobile plans, fitness memberships, insurance, energy, streaming and more. Add a contract once, stay informed and avoid unnecessary renewals.

⚡ QUICK START WITH CONTRACT TEMPLATES
Choose from templates for common contracts such as mobile plans, internet, fitness, streaming, insurance, energy and the Deutschlandticket. Suggested terms and notice periods can be adjusted to match your actual contract.

⏰ CLEAR DEADLINE COUNTDOWN
Enter the minimum term, renewal and notice period. Fristenfuchs calculates when your cancellation should arrive. Green, amber and red make urgent deadlines easy to spot, with local reminders at the times you choose.

Select a normal notification or an especially noticeable optional full-screen reminder. Full screen requires your Android permission; otherwise the normal notification is shown automatically.

📋 COMMON GERMAN CONTRACT MODELS
Supports minimum terms followed by flexible cancellation, fixed renewal periods, monthly cut-off dates, contracts that can be cancelled at any time and contracts that end automatically. The app is designed primarily for contracts governed by German rules.

💶 COSTS AT A GLANCE
View monthly and yearly fixed costs and see how they are distributed by category.

📱 HOMESCREEN WIDGET AND CALENDAR
Keep your next deadline visible on your homescreen or prepare an additional event for the calendar app of your choice.

📄 CANCELLATION WORKFLOW (PREMIUM)
Review and edit a cancellation email subject and message, prepare an email, copy or share the text, create a PDF draft and locally document when and how it was sent. Optional follow-up reminders help you remember to check for confirmation.

💾 LOCAL BACKUP FOR PHONE CHANGES
Create a local backup file and restore it on another device — without an account or forced cloud storage. CSV export is included with Premium.
