Memory Privacy and Deletion
Your memories are yours. This article covers what's stored, who can access it, how to delete it, and the platform's privacy commitments.
What's stored
For each user account:
| Storage | What | Where |
|---|---|---|
memory_facts | Discrete claims extracted from your conversations | Postgres, scoped to your user_id |
memory_summaries | Per-conversation summaries | Postgres, scoped to your user_id |
recall_chunks | Embeddings for semantic search | Postgres, scoped to your user_id |
All three tables have your user_id as the primary scope. Cross-user access is impossible at the query layer.
Who can read your memories
- You — via the model when recall surfaces them, via Settings → Memory (when the explorer ships), via export
- Nyquest operators — authorized access for requested support, safety/security investigations, or legal obligations, as described in the privacy policy. Conversation access is audited.
- Other customers cannot access your memories. Providers may process context sent for inference or embeddings as described in the privacy policy; memories are not sold.
Training policy
Nyquest does not use your conversations or memories to train models. Inference providers process the context sent to them under their own terms and data settings; BYOK uses your provider account. This statement is not a guarantee about every provider’s separate policy.
The platform routes prompts to model providers (OpenAI, Anthropic, etc.) for inference. Each provider has their own data policies for the prompts you send through them — some opt out by default, some require explicit settings. If you're sending sensitive content, BYOK with a provider that has a strong no-training policy is the safest path. See your provider's specific policy for details.
Nyquest itself does not train models. We don't have the infrastructure for it and it's not in our business model.
Deletion options
Delete all memory
Settings → Privacy → Delete Memory & Knowledge (full label).
Wipes:
- All facts (active + superseded)
- All summaries
- All recall chunks
- All embeddings tied to artifacts
This is irreversible. The model has no memory of past conversations after this. Your conversations themselves are NOT deleted — only the memory layer derived from them.
To trigger this, you must type "delete all memory" as a confirmation phrase. We require this confirmation specifically to make accidental deletes impossible.
Delete a specific conversation
Right-click conversation → Delete.
Deletes:
- The conversation's messages
- The conversation's summary
- Recall chunks tied to that conversation
Facts extracted from the conversation are NOT auto-deleted, because facts are de-duplicated across conversations (a fact like "user prefers Rust" might have been mentioned in 5 conversations and shouldn't disappear when one is deleted). Use Delete Memory if you want a complete wipe.
Can I turn recall off?
Recall is enabled for signed-in browser chat. PAT chat-completion requests are stateless and skip memory recall. For browser chat, there is no toggle that disables it — the only thing that skips recall is the length gate: messages shorter than four words don't trigger a semantic lookup. Your recent messages, the conversation summary and your durable facts are always provided.
If you want a specific fact to stop influencing replies, forget that fact (below) rather than looking for a global switch.
Per-fact deletion
Settings → "What Nyquest remembers". Every stored fact is listed there with a Forget button. Click it, confirm, and that single fact is archived and dropped from recall permanently — the rest of your memory is untouched.
The same panel has a Pin control, which does the opposite: a pinned fact never decays, is skipped by the daily consolidation pass, and is prioritised during recall.
If a forgotten fact somehow reappears, or you need it purged from backups too, talk to a real human.
Export your memories
Settings → Privacy → “Download my data” generates a JSON file, saved straight to your browser (nothing is emailed), containing:
- All your conversations
- All your projects
- Server-stored artifacts associated with your account; local vault items require a separate vault export
- All your memory facts and summaries
The export is for your records and portability — it includes raw stored data so you can verify what's been remembered or migrate to another tool.
The export downloads in your browser. Keep the downloaded file secure. The local artifact vault and generated-media file bytes are not a substitute for a separate file backup.
Storage and transport
Connections to the hosted service use HTTPS. Memory text must be readable by the service for recall; it is not end-to-end encrypted. Backup archives are encrypted, and stored provider keys use application encryption. BYOK changes who bills provider inference; it does not encrypt or eliminate the conversation history stored by Nyquest.
For work that must stay entirely on infrastructure you control, evaluate the self-hosted engine and your chosen provider configuration.
Account deletion
Settings → Account → Delete account.
Triggers permanent deletion of:
- All memories (facts, summaries, recall chunks)
- All conversations
- All projects
- All artifacts
- Stored API keys (encrypted)
- Every file you generated in the Studios (images, audio, music, video)
- Wallet balance — forfeited, not refunded. Deletion is blocked while you hold a balance, and proceeding means permanently waiving it. Email legal@nyquest.ai for a refund before you delete.
All of the above is purged from the database immediately — there is no 24-hour grace period. Backup copies expire under the backup retention schedule; deletion from the live service is not instantaneous removal from every existing backup.
Backup copies and deletion questions
An encrypted backup made before deletion can still contain the deleted data until that backup expires. Contact legal@nyquest.ai for the applicable retention details or an account-specific deletion request. Do not treat a support acknowledgement as a certificate of deletion from every storage system.
