# Introduction

> Subscription Manager is a local-first app for tracking recurring subscriptions, optional cloud sync, payments, reminders, and API automation.

# Subscription Manager

Subscription Manager helps users track recurring subscriptions, renewal dates, spending trends, and category-level analytics.

The app is local-first by default. Without any hosted services, data stays in the browser. When you need accounts, cloud sync, payment activation, server-side reminders, or automation, you can enable Supabase, Stripe, Netlify Functions, Bark, and the public API.

## What you can do

* Track subscriptions with category, amount, currency, billing period, and renewal date.
* Review monthly and yearly totals in a selected base currency.
* Convert between CNY, USD, EUR, JPY, GBP, AUD, CAD, CHF, HKD, and SGD.
* Sort and filter subscriptions by name, amount, renewal date, category, or creation date.
* Manage built-in and custom categories.
* Use AI capture to propose creates, updates, deletes, and batch updates from text or screenshots.
* Import and export subscription data as JSON.
* Use optional Supabase authentication and multi-device sync.
* Send optional Bark push reminders for upcoming renewals.
* Create Developer API keys for subscription CRUD automation.
