Scanalyze is designed as a multi-tiered application involving client-side, server-side, and database components. Each of these elements has specialized tasks and together they form a cohesive ecosystem for effective grocery expense tracking.
The mobile application serves as the user interface and is responsible for capturing grocery receipts through the device's camera. It utilizes Optical Character Recognition (OCR) to extract textual data from these receipts. The app also handles user authentication and data visualization through various graphs and charts.

Key Features:
- Receipt scanning
- Data visualization with charts
- Receipt history
The web server acts as the intermediary between the mobile application and the database. The server processes the OCR data received from the mobile application and feeds the database. It is the server responsibility to link (index) the abbreviated products on the receipt to the existing product in the database. Additionally, the server leverages user data from the database to generate statistics, which are made accessible to the mobile application via its API. The server also manages user authentication tokens. Want to learn more? Check this out
Key Features:
- Data processing and analysis
- Receipt - database indexation
- API endpoints for client-server communication
The database stores detailed information about various grocery products, including their descriptions, categories, and indicative prices. This data is queried by the web server whenever a new grocery receipt is processed.Want to learn more? Check this out
Key Features:
- Storage of product descriptions and categories
- User data management
- Scalable data schema
Application that scrapes data from Coop, Migros, Aldi and Lidl stores to feed the database.

We appreciate your interest in contributing to our project! However, please note that we are currently not accepting contributions from outside our development team. Here's why:
- Project Maturity: The project is in a nascent stage, with various core features still under development. Until it reaches a more mature state, we are limiting contributions to our internal team.
- Management Constraints: As a student-run project, we have limited time and resources to manage pull requests and issues from external contributors.
- Hosting Limitations: Parts of our project are hosted on AWS Elastic Beanstalk. Given that we are currently funding this out of pocket, we are not yet prepared to deploy the infrastructure for public usage.
- Incomplete Features: Account management, among other features in the Android app, are not fully implemented. We believe that opening the project up for contributions at this stage could lead to unnecessary complexity.
We understand the enthusiasm and interest to contribute, and we do plan on making the repository publicly accessible for contributions once it's mature and we are ready to manage it efficiently. If you have any questions or would like to be notified when we are accepting external contributions, feel free to contact us.
Thank you for understanding.
