Terms of Service
About these terms
DNG Software Pty Ltd provides Sightline 365. These terms describe use of the desktop software, licensing services and this website. If you use the product for an organisation, you must have authority to do so and to accept the applicable purchase terms on its behalf.
Licence and device seats
Subject to these terms and your entitlement, DNG Software grants you a non-exclusive licence to install and use Sightline 365 for authorised work. Collection entitlements are associated with your Microsoft 365 tenant. Paid plans include the number of seats stated in the applicable offer. Seats are enforced through active device registrations within that tenant; they do not mean unlimited installations with simultaneous collection access. Release an unused device through the available device-management controls or contact support when changing computers.
Free discovery and collection trial
Discovery includes searching connected sources you can access, filtering, previewing and opening originals. It remains free after a collection trial ends. Installing, signing in and searching do not start the trial. ZIP collection and optional Microsoft 365 destination copying require an active collection trial or paid entitlement.
The collection trial starts only when you explicitly request it in the app. It lasts up to 21 days with a 500-operation budget and ends when either limit is reached. An operation is a unit recorded by the collection/copy workflow, not a search query. The app shows trial status and remaining budget. No payment card is required to start the trial, and it does not automatically become a paid subscription.
Acceptable use
You may use Sightline 365 to search accessible Microsoft 365 content and create local ZIP copies, or explicitly enable tenant destination copying, only where you hold appropriate permissions and authorisation. Protect local content and follow your organisation's retention, storage and sharing policies. You may not use the software to bypass Microsoft access restrictions or collect information unlawfully. Except to the extent permitted by applicable law, you may not reverse-engineer, redistribute or resell the software or its licences without a written agreement from DNG Software Pty Ltd.
Content, permissions and collection limits
You retain your rights in your content. You are responsible for the authorisation, notices, legal basis, retention and security required for your use of it. Access depends on Microsoft permissions, tenant consent, service availability, search indexing and the sources you connect. Own OneDrive and own mailbox connections are not a promise of tenant-wide mailbox or custodian-wide discovery.
Search results are not a guarantee of exhaustive discovery. Review incomplete searches, per-item failures, collection summaries and original sources. Sightline 365 does not replace Microsoft Purview legal holds, formal compliance workflows, or independent legal advice. Reports and hashes are technical records, not legal certification or a guarantee of admissibility.
A ZIP contains copies outside Microsoft 365. Protect downloaded content, previews and local records under your organisation's policies; do not assume Microsoft 365 access controls or sensitivity protections automatically apply to those copies. Optional destination copying can change content in the selected Microsoft 365 location. Confirm selections and destinations, retain appropriate backups, and verify outcomes.
Subscriptions, payment and cancellation
The applicable offer and Stripe checkout identify the plan, seat allowance, billing interval and amount. Review the currency and any tax shown before authorising payment. Subscriptions renew at the end of each billing period unless cancelled through the billing portal before renewal. You can open the portal from the app. Cancellation stops future renewals; it does not by itself request a refund or erase local content.
Paid plans advertise unlimited collection operations rather than the trial's 500-operation budget. Microsoft permissions, API throttling, technical capacity, device-seat limits and lawful-use requirements still apply. Availability and performance of Microsoft or other third-party services are not under DNG Software's control.
Founder lifetime offer
Where available, the advertised Founder offer is a one-time purchase for one seat, with a perpetual licence, future updates and major-version upgrades as stated in the offer. It is not a renewing subscription. The offer is limited to the first 100 customers and includes Founder recognition and a direct line to the product team, as advertised on the pricing page.
Refunds and mandatory consumer rights
Discretionary refund requests are considered case by case; contact support within 30 days of a charge. This is not a guaranteed 30-day money-back offer. That time limit does not restrict any statutory right.
Nothing in these terms excludes, restricts or modifies any consumer guarantee, right or remedy that cannot lawfully be excluded, including under the Australian Consumer Law where it applies. Statutory remedies are separate from any discretionary refund policy.
Updates, support and privacy
The Windows app can check for and download signed updates. Software features may evolve as Microsoft services change. Plan-specific support is described in the applicable offer; these terms do not introduce a guaranteed response time or service-level agreement. Information handling, local files and optional support reports are described in the Privacy Policy.
Warranty & liability
Subject to rights and liabilities that cannot lawfully be excluded, the software is provided "as is" without additional warranties of uninterrupted, error-free operation, exhaustive results or fitness for a particular legal or compliance outcome. To the extent permitted by applicable law, the contractual limit on DNG Software's total liability relating to the software is the fees you paid for it in the 12 months before the claim arose. This limit does not override mandatory rights.
