Hardcoding sensitive information

[rohinee18tech]

1. No Use of Environment Variables: One of the major issues raised in the repository is the lack of token management via environment variables, which makes the application less secure
2. Potential for Memory Overuse: There’s feedback suggesting that the inclusion of weather-related visuals or GIFs could overload memory and GPU, impacting the performance on less capable devices
3. No Formal Security Policy: The repository lacks a clear security framework, such as SECURITY.md, which is essential for large-scale applications that deal with third-party data or user-generated content
