Chat migration stores plaintext with e2ee level, breaking all reads
migrate_chats_level_batch skips encryption for target_level == 'e2ee', leaving migrated_text as plaintext but stamping data_protection_level: 'e2ee' on the document. However, _prepare_message_for_read now decrypts for both 'enhanced' and 'e2ee' levels:
if level in ('enhanced', 'e2ee'):
return _decrypt_chat_data(message_data, uid)When a migrated message is subsequently read, encryption.decrypt() is called on plaintext — it expects base64-encoded AES-GCM ciphertext, so it will raise an exception for every single migrated message, making the entire chat history unreadable after the migration completes.
The inline comment "client re-encrypts on next write" is incorrect for chat: messages are server-encrypted at both levels (the client never encrypts chat). New writes will be server-encrypted correctly, but existing migrated messages will be permanently broken.
The fix is to apply server-side encryption during migration for 'e2ee' the same way 'enhanced' does:
if target_level in ('enhanced', 'e2ee'):
if isinstance(plain_text, str):
migrated_text = encryption.encrypt(plain_text, uid)| @@ -88,7 +128,8 @@ def update_goal(uid: str, goal_id: str, updates: Dict[str, Any]) -> Optional[Dic | |||

update_goal return value is silently discarded by the @prepare_for_write decorator
The prepare_for_write decorator always returns original_data (the unencrypted updates dict passed by the caller), ignoring whatever the wrapped function returns:
# From database/helpers.py
func(*bound_args.args, **bound_args.kwargs)
return original_data # ← the function's return value is thrown awayThis means the two lines at the bottom of update_goal:
updated_doc = goal_ref.get().to_dict()
return _prepare_goal_for_read(updated_doc, uid)…are dead code. Every caller of update_goal receives the original updates input dict (a partial set of fields, already encrypted by the decorator by the time it's captured) instead of the complete, freshly-read goal document.
Either:
- Remove the dead
goal_ref.get()+_prepare_goal_for_readlines and document thatupdate_goalnow returns the caller's input, or - Move the read-back logic outside the
@prepare_for_writeboundary (e.g., via a separate helper or by not using the decorator here), so the full decrypted document is returned.

🚨 NOT SAFE TO MERGE — Critical data corruption and security issues present. Critical Blockers1. Migration to E2EE will break ALL chat message reads (chat.py:557)The existing review comment is correct. if level in ('enhanced', 'e2ee'):
return _decrypt_chat_data(message_data, uid)When Fix: Apply server-side encryption during e2ee migration same as enhanced: if target_level in ('enhanced', 'e2ee'):
if isinstance(plain_text, str):
migrated_text = encryption.encrypt(plain_text, uid)2. Same migration bug in conversations/photos (conversations.py:~850)Photo migration to e2ee stores plaintext: elif target_level == 'e2ee':
# E2EE: store plaintext during migration; client handles encryption
photo_update_payload['base64'] = plain_photo_data['base64']But photos are fetched by 3. Memory migration leaves plaintext with e2ee flag (memories.py:~280)Same pattern: comment says "client will re-encrypt on next write" but:
4. Conversation transcripts have no E2EE path (Already reported)The existing comment about conversations.dart:78 is accurate — transcripts are created entirely server-side with no client encryption opportunity. This contradicts the PR description's claim of "E2EE for memories." 5. edit_memory doesn't handle E2EE level (memories.py:~170)def edit_memory(uid: str, memory_id: str, value: str):
# ...
if doc_level == 'enhanced':
content = encryption.encrypt(content, uid)E2EE memories edited through this endpoint will be stored as plaintext. Design ConcernsArchitecture mismatchThe PR description says "True E2EE for memories — encrypted on-device before reaching the server" but the migration code contradicts this by storing plaintext during migration and expecting "client re-encryption on next write." This reveals the implementation is incomplete. Silent fallbacks mask errorsBoth CI StatusBuild status shows "pending" with 0 checks — no test results visible for this PR.

I have to disagree that this is useless from a security perspective. This PR does not claim full end-to-end encryption for all data. The intended model is:
If your concern is that the guarantees are still too mixed or unclear, that’s fair. In that case, it would help to know what specific change would make this acceptable. |
|
I do understand your point though, so i won't be mad if you actually decide to not merge it. |
|
do u understand that your pr even breaks the services since none of them are valid points (check the 3rd screenshot again), not counting the impl quality or security mindset. |

I know this looks like a big PR, but this is mostly because of missing translations
Proof
(localization missing from the screenshots, are added after taking the screenshots tho)
Summary
Implements comprehensive data encryption for Omi:
Security Model
Why not full E2EE for everything?
Conversations and chat require server-side processing (Deepgram for transcription, LLM for chat responses). The server must see plaintext during processing, but all stored data is encrypted at rest. True E2EE for these would require on-device transcription — a future enhancement.
