add anonymous mode

[Ritikavarshney-hub]

Which issue does this PR close?

• Closes Anonymous Mode (No Data Stored) #75

Rationale for this change

This change introduces Anonymous Mode to enhance user privacy. Users may prefer to interact with the mental health companion app without storing any sensitive data (like chats, mood entries, or journals). Adding this feature helps build trust and ensures compliance with privacy-first principles.

What changes are included in this PR?

Added a toggle in the sidebar for "Anonymous Mode"

Updated main.py, chat_interface.py, and utils.py to conditionally disable:

Loading/saving of conversation history

Any future journaling or mood tracking data persistence (if implemented)

When enabled:

No conversations or inputs are saved

Chat history is not loaded from disk

Visual indicator appears confirming anonymous mode is ON

@Ritikavarshney-hub Thanks for reaching out, and sorry for the delay, I got caught up with a lot of stuff since yesterday. Based on what I know from the recent changes in the app, the conversations are stored using the save_conversations() and load_conversations() functions in core/utils.py to handle reading/writing the conversations to a JSON file (data/conversations.json).

For further info regarding this you can go through PR #20

And in general Streamlit uses st.session_state to store information, including chat history, for the duration of a single browser session.

Feel free to ask me or @pkbros about further confusions if any or if any guidance is needed. Looking forward to your PR!
