Retention summaryUpdated app (from 18 August 2026): chat history is retained so chats can be revisited; saved memories are separate and turning memory off does not delete existing memories.

Pricing summaryPersonal Copilot is available without an organisational licence. Without a Microsoft 365 subscription, advertising may appear. Paid Microsoft 365 Premium/Pro home plans are a different SKU and do not convert this into a DPA-covered Online Service.
Legal content coverageNot a licensed primary-law research product. Web search grounds on publicly available web content via Bing.
Australian presenceYes — Microsoft has an Australian commercial presence. Personal Copilot processing location is not stated on the individual-app privacy pages. Do not infer AU residency from Microsoft 365 organisational commitments.

Define the configuration, people, information and tasks being assessed.

Updated personal app versus older app and M365 home

Not confirmed

This profile covers the updated Microsoft Copilot app available from 18 August 2026 when signed in with a personal Microsoft account. The older-app Privacy FAQ still permits conversation activity for model training unless opted out. Copilot inside home Microsoft 365 apps and Entra work/school sign-in have separate documentation. Cowork multi-step tasks and model choice vary by subscription.

Ask: Confirm we are on the post-18 August 2026 app, signed in with a personal account only, and that no work files are uploaded.

Consumer cloud; region not published

Not confirmed

The individual-app privacy pages do not name a storage or inference region. Do not carry over Microsoft 365 Advanced Data Residency or EU Data Boundary commitments from the organisational Copilot profile.

Ask: Where are personal Copilot chats, files and memories stored and inferred for an Australian user?

Chat, memory, Cowork, web search, ads

Public claim only

Chat with history; optional saved memories; web search (toggle); shared experiences with Bing/Edge/MSN; advertising if there is no Microsoft 365 subscription; Cowork for multi-step tasks; user can choose among leading models. Feature set varies by subscription.

Ask: Which of memory, web search, shared experiences, Cowork and model choice will be on for our testers?

US consumer terms; no AU residency commitment

Public claim only

Use is under the Microsoft Services Agreement and Copilot Terms of Use, plus the Microsoft Privacy Statement. Those are consumer contracts, not the organisational DPA. Processing location for personal Copilot is unpublished. Older-app FAQ excludes some countries from training; Australia is not on that exclusion list.

Ask: If a lawyer uses personal Copilot on client facts, which country holds the chat and does APP 8 consent cover Bing and ads?

Adoption and implementation

Record the practical work needed to introduce and maintain the software.

Free consumer product; paid home M365 is separate

Public claim only

Personal Copilot is offered without an organisational seat licence. Advertising may appear without a Microsoft 365 subscription. Home Microsoft 365 Premium/Pro pricing is a different product page and does not create enterprise data protection.

Ask: Will anyone in the firm use a paid personal subscription, and is that still a consumer MSA?

Bing, Edge, MSN shared experiences

Public claim only

Shared-experience setting can connect Copilot chats with Bing, Edge and MSN personalisation in both directions. Edge browsing activity has a separate advertising/experiences control. There is no Entra admin plane, Graph grounding or Purview on this plan.

Ask: Require shared experiences off if personal Copilot is used at all, and confirm no work mailbox is connected.

Consumer support only

Not confirmed

No organisational Unified/Premier SLA applies to a personal Microsoft account. Support is consumer-grade via Microsoft account help.

Ask: Treat personal Copilot as unsupported for client work; do not open firm tickets against it.

Quality and human effort

Compare complete work at the required quality, including checking and correction.

Terms warn responses may not be unique or accurate

Public claim only

Copilot Terms of Use: responses may not be unique; others may receive the same or similar output. No independent hallucination study for the personal app was found. Users are expected to review content they publish.

Ask: Ban personal Copilot for client advice, affidavits and court work regardless of subscription.

Personal productivity only

Not confirmed

Fit for personal drafting and web Q&A. Unfit for confidential client files: consumer MSA, advertising, shared Bing/Edge experiences, unpublished region, and (on the older app) default model training. Cowork can take multi-step actions on the user's machine/files.

Ask: Is personal Copilot permitted on any firm device, even for non-client tasks?

Data, controls and requirements

Compare the actual configuration with firm, client and jurisdiction requirements, supported by evidence.

Do not put client content in a personal account

Not confirmed

A personal Microsoft account is not a firm tenancy. Uploading client documents or pasting matter facts creates a disclosure to Microsoft as a consumer-service controller, plus optional Bing, ads and (older app) training. No client-disclosure template exists because this is not an authorised firm tool.

Ask: Prohibit client content in personal Copilot and say so in the acceptable-use policy.

Microsoft-hosted; user may choose among models

Public claim only

Overview: users can choose between leading AI models depending on subscription. Providers and regions are not named on the individual privacy pages. Do not assume Azure OpenAI organisational terms.

Ask: Which models does the updated personal app actually call, and in which country?

Updated app: no foundation-model training; older app: opt-out

Public claim only

Updated app activity-history page: prompts, responses and file contents are not used to train foundation models. Older-app FAQ: conversation activity, including uploaded files, is used for generative-AI training unless the user opts out or is in an excluded country (Australia is not listed). Do not mix the two statements.

Ask: Confirm every user is on the updated app; if anyone is on the older app, require training opt-out before any use.

Optional feedback; not for foundation-model training on the new app

Public claim only

Updated app: optional customer feedback may improve Copilot like other Microsoft 365 services but is not used to train foundation models. The linked feedback process can request additional prompts, responses, content samples and logs. Older app treats conversation activity itself as training data unless opted out.

Ask: Disable feedback and do not submit chats that contain work content.

Chat history plus separate memories

Public claim only

Updated app retains chat history. Saved memories persist until deleted; turning the Saved memories toggle off does not delete existing memories. Older-app FAQ: uploaded files kept no longer than 18 months. No numbered live-chat day count is on the updated activity-history page.

Ask: What is the default retention for chats, memories, logs and backups on the updated app?

Per-chat delete; dashboard export; memories separate

Public claim only

Users can delete individual chats and export or delete activity history via the privacy dashboard. Memories must be deleted under Personalization → Manage; off does not equal delete. Previously used training data on the older app cannot be unlearned from a model.

Ask: After deleting chats and memories, what remains in backups and advertising/Bing shared-experience stores?

Personal Microsoft account only

Public claim only

Sign-in is a personal Microsoft account. There is no Entra Conditional Access, sensitivity labels or admin MFA enforcement for this plan. Anyone with the password can see chat history and memories.

Ask: If the firm allows personal Copilot on a device, require a unique personal account never used for work mail.

No SOC/ISO claim on the personal-app pages

Not confirmed

The individual Copilot privacy articles do not cite SOC 2 or ISO 27001 for the consumer app. Organisational Copilot certifications do not automatically cover personal accounts.

Ask: Do not treat Microsoft 365 Copilot ISO/SOC reports as covering personal Copilot.

MSA + Copilot Terms of Use; user indemnifies Microsoft

Public claim only

Microsoft Services Agreement and Copilot Terms of Use (personal). Terms do not apply to Entra accounts. User agrees to indemnify Microsoft for use, sharing or publication of prompts, responses or creations. Responses may not be unique. No organisational liability cap or DPA.

Ask: Confirm personal Copilot is outside our Microsoft Customer Agreement and must not be used for firm work.

Consumer Privacy Statement only

Not confirmed

No 72-hour organisational notification. Breach handling follows the Microsoft Privacy Statement for consumer services, not the Online Services DPA.

Ask: Do not rely on personal Copilot for notifiable client data.

Edge import; shared Bing/MSN

Not confirmed

Controls include importing browser data from Edge and One shared experience with Bing/Edge/MSN. Each is a disclosure path from Copilot chats into other Microsoft consumer products.

Ask: Keep Edge import and shared experiences off on any device that might see work content.

Web search on by default; user toggle

Public claim only

Copilot can search the web for current public information. Users can turn Web search off under Personalization. Queries are not described as DPA-covered.

Ask: If the app is used at all, require web search off unless the task is purely public-web research with no client facts.

User must review before publishing

Public claim only

Terms: user is responsible for use of prompts and responses; indemnifies Microsoft. No in-product lawyer sign-off. Unsuitable as a supervised legal workflow.

Ask: Keep personal Copilot out of any workflow that produces client-facing work product.
