These Terms of Service (“Terms”) are a legal agreement between you (“you”, “User”) and Sentria (“Sentria”, “we”, “us”, or “our”). By creating an account, using the Sentria application (mobile, desktop or web) or otherwise accessing the Service, you agree to be bound by these Terms and our Privacy Policy located at [here] (the “Privacy Policy”).

Note on third-party providers: We use third-party service providers to operate the Service (cloud hosting, storage, sync, payment processors). See the Third-Party Services section for details and options for obtaining a Data Processing Addendum.

Definitions

  • Account: your user account on Sentria.
  • Content / Notes: text, attachments, files, and other data you create, upload, or store using the Service.
  • Service: Sentria’s software and services that provide local note-taking, optional cloud sync, backup, and related features.
  • Payment Provider: the third-party provider that processes payments for subscriptions and purchases (for example, platform stores or web payment processors).
  • Subscription: a paid plan that unlocks cloud features subject to plan limits and quotas.

Eligibility

You must be at least the minimum age required by applicable law to use the Service. If you are creating an Account for a business or organization, you represent and warrant that you have the authority to bind that entity to these Terms.

Account Registration and Acceptance

You must create an Account to use cloud features. When you register, you must provide truthful information and keep your credentials secure. You are responsible for activity that occurs under your Account.

When required by law or the payment flow, you will be asked to accept these Terms (for example, at account creation or checkout). We will record your acceptance with the version and timestamp.

Service Description; Paid vs Free

  • Free tier: Provides local note-taking functionality on the device. Local notes remain on the device unless you choose to upload or create an Account and enable cloud sync.
  • Paid tiers (Subscriptions): Provide cloud sync, remote backups, attachments, and other features described on the pricing page. Plans are subject to per-plan quotas (per-file and total storage) and limits described on the pricing page. Server-side quota enforcement may reject or defer uploads that would exceed the allowed limits.

We may change features or discontinue functionality, subject to notice and applicable law. We do not guarantee uninterrupted access; see the Termination and Suspension section.

Subscriptions, Trials, Billing and Refunds

  • Store purchases: Purchases made through platform stores (Apple App Store, Google Play) are subject to the store’s terms and refund policies. Contact the store for questions about billing or refunds for purchases made through that store.

  • Web purchases: Purchases made on our website are processed by Paddle, which acts as the merchant of record for those transactions. Refunds are provided in accordance with Paddle’s Invoiced Consumer Terms. Refunds are issued at Paddle’s sole discretion and may be refused in cases of fraud, refund abuse, or other manipulative behavior.

  • Refund window: You have the right to cancel your purchase within 14 days from the day after the date of purchase, with no exceptions or conditions, without any question asked for.

  • Trials & introductory offers: Trials and introductory pricing, if offered, are described on the pricing page. Trials are limited to one per eligible account unless otherwise stated. Trial terms (duration, renewal rules) are displayed at the point of purchase.

  • Automatic renewal: Subscriptions automatically renew until canceled. You are responsible for canceling before the renewal date if you do not wish to be charged.

  • Failure to pay: If a renewal payment fails, we may suspend access to paid features until payment is resolved.

  • Support: Contact billing@sentrialabs.com.

User Content; Ownership; License

  • Ownership: You retain all rights, title and interest in your Content.
  • License to us: By uploading or storing Content, you grant Sentria a worldwide, non-exclusive, royalty-free license to copy, store, transmit, display and otherwise process your Content solely to provide and improve the Service (including synchronization across devices and backup). We do not claim ownership of your Content.
  • Responsibility: You are responsible for the legality of your Content and for maintaining adequate backups. We recommend you periodically export Content for your records.

Export, Backup, Deletion, and Retention

  • Export: The Service provides tools to export your Content. You are responsible for keeping copies where required.
  • Deletion and retention: When you delete an item or your Account, we will remove Content in accordance with our retention policy and applicable law. Some backup copies may remain for a limited time for operational resilience or legal compliance.
  • Account termination: On account deletion, we will schedule removal of your Content. If you cancel a paid subscription, we may retain Content for a grace period described in the Help Center to allow recovery.

Third-Party Services and Data Processing (subprocessors)

We use third-party providers to operate the Service (hosting, storage, synchronization, analytics, payments). These providers may process or store your Content and metadata as necessary to provide the Service.

Public (generic) clause — recommended for the public Terms:

We use third-party service providers (subprocessors) such as cloud hosting, storage, synchronization, analytics, and payment processors. These providers process data on our behalf only to support the Service’s operation. For information about how we handle personal data, see our Privacy Policy. Enterprise customers may request a list of subprocessors or a Data Processing Addendum by contacting legal@sentrialabs.com.

Optional explicit clause (use in DPA or upon request):

On request, we will provide an up-to-date list of subprocessors (e.g., hosting, sync, and payment providers) and an executable Data Processing Addendum for customers that require it. To request details, contact legal@sentrialabs.com.

Recommendation: Keep the public Terms generic and provide a private subprocessor list / DPA to enterprise customers. This approach balances transparency and operational confidentiality.

AI, automation, and derived content

If we provide AI features, we will disclose:

  • that you are interacting with an AI system,
  • the intended functionality and limitations,
  • whether and how your Content is used to produce AI outputs or to train models,
  • and that you remain responsible for verifying AI outputs.

We may offer ability to opt-out of data use for training where required by law or product design.

Acceptable Use

You must not use the Service to:

  • Upload illegal, infringing, abusive, or harmful content,
  • Interfere with the Service or violate rate limits,
  • Attempt to bypass quotas, billing, or security measures,
  • Use the Service as a general-purpose file storage service beyond normal note-taking use.

We may suspend or terminate accounts that violate this section. We may also impose limits or ask customers to migrate to a custom plan for large / unusual usage patterns.

Security

We employ commercially reasonable measures to protect Content in transit and at rest. We do not warrant absolute security. If you wish to use additional encryption or store sensitive regulated data, contact our sales/legal team for guidance.

Disclaimers and Limitations of Liability

The Service is provided “AS IS”. Except where prohibited by law, we disclaim all implied warranties. Our liability for direct damages is limited to the greater of (a) the total subscription fees paid by you to Sentria in the twelve (12) months prior to the claim or (b) USD 100. We are not liable for consequential, incidental, or punitive damages.

Indemnification

You agree to indemnify Sentria from claims arising from your Content, your breach of these Terms, or your misuse of the Service.

Termination

We may suspend or terminate Accounts that violate these Terms or where required by law. Upon termination for cause, fees are not refundable except as required by law or applicable payment provider policy.

Governing Law; Dispute Resolution

These Terms are governed by the law of [YOUR JURISDICTION — e.g., State of California, USA]. Disputes shall be resolved [choose: in court of competent jurisdiction / by arbitration — select based on legal advice]. If you are in the EU, consumer rights may vary by country.

Changes to Terms

We may update these Terms. For material changes, we will provide notice (in-app or email) and post the new Terms. Continued use after notice constitutes acceptance. We track and store acceptance events for auditability.
