+# Manifesto
+
+## 1. Data Ownership :fontawesome-solid-key:
+
+User owns the data. It should be possible to migrate all the data to
+another app or service. Paisa will strive to make this as easy as
+possible by choosing open standards and formats.
+
+> [Ledger](https://ledger-cli.org/) text format is used to store all the transaction data.
+
+## 2. Privacy :simple-gnuprivacyguard:
+
+User's data is private. Paisa will not collect or send any data to any
+server[^1]. Paisa will not use any third party analytics or tracking on
+the app[^2].
+
+> Paisa's source code is open source and could be audited by anyone.
+
+## 3. Longevity :octicons-infinity-24:
+
+The app should be available for a long time. It takes a lot of effort
+to collect and maintain the transaction data. The app should not just
+disappear one day. Paisa will strive to avoid unnecessary dependencies
+and build a self contained app.
+
+> Paisa is licensed under AGPL v3, which helps with this issue to some
+> extent. I have yet to figure out a solution to make the app
+> development and maintenance process sustainable in the long
+> term. But rest assured, any decision that would be made related to
+> this will not override the first two points.
+
+
+[^1]: Paisa fetches commodity price information from third party
+    servers. Since Paisa will send the commodity identifier to the
+    server, the third party server might be able to connect the
+    commodity list with the user's IP address. This is an opt-in
+    feature, as you have to explicitly configure Paisa to fetch
+    price. VPN could be used if you want to avoid this.
+
+[^2]: This doesn't include the website paisa.fyi, which is hosted on
+    third party servers and has consent based analytics.
