Security, Built-In

Secure file protection

Protection that stays with the file.

Turn a file into a protected shareable asset designed to stay protected as it moves. The standard protection flow keeps file contents local in your browser and produces a self-contained HTML unlock file that can work offline, while stricter account-linked workflows add backend-enforced controls when you need them.

Standard workflow

  1. Protect — choose a file and encrypt it with AES-256-GCM plus Argon2id key derivation.
  2. Share — download a self-unlocking HTML file that recipients can open in modern browsers.
  3. Stay in control — keep file contents local in the standard flow, or use stricter account-linked controls where enabled.

Current public posture

  • Base can be used without an account, while signed-in accounts unlock GateSeal vault access and paid upgrades
  • No file contents are uploaded in the standard protection flow
  • Strict exports may register policy and unlock metadata with the backend for expiry, incorrect attempts limits, and tracking, but not the file contents themselves
  • Recipients can open the protected HTML in modern Chrome, Safari, Firefox, and Edge without apps, plugins, or recipient accounts

What the public product is for

SentinelLolge is built for contracts, financials, API keys, private documents, code, media, and other files that need confidentiality to stay attached to the asset even as it moves across inboxes, drives, and offline handoffs.

Privacy Policy

Privacy policy for the current website service.

This policy governs how SentinelLolge handles personal information in connection with the current website service. Applies to the public website service, including account-linked features and paid-plan flows where enabled. Effective date: May 7, 2026.

Information covered by this policy

This policy applies to personal information SentinelLolge collects, receives, stores, uses, discloses, or otherwise handles in connection with the website service. It does not govern third-party sites, services, or payment environments except to the extent SentinelLolge directs information into those environments as part of a service workflow.

Information we may collect

Depending on how you use the service, SentinelLolge may process account and profile details, contact details, authentication information, payment and billing records, customer support communications, device and browser information, usage and event data, and settings or metadata associated with protected-sharing workflows. SentinelLolge may also process customer-provided content-related metadata where that is necessary to operate access controls, support account features, or maintain service records.

Information that may remain local

Certain website workflows are designed so protected file contents are handled locally within the browser rather than routinely uploaded as raw source content to the service. Even where content remains local, related metadata, event data, account state, or control information may still be processed by SentinelLolge where needed to provide account-linked features, security controls, billing state, or service operations.

How we use personal information

SentinelLolge may use personal information to provide and operate the service, authenticate users, maintain account state, deliver paid access, administer sharing controls, prevent abuse, enforce service policies, maintain security, respond to requests, provide support, measure product usage, improve reliability, comply with legal obligations, and protect the rights, safety, or integrity of SentinelLolge, its users, and third parties.

How we disclose information

SentinelLolge may disclose personal information to service providers, infrastructure providers, analytics providers, identity providers, payment providers, professional advisers, corporate transaction participants, or public authorities where reasonably necessary for service delivery, security, billing, legal compliance, or protection of rights.

Cookies, local storage, and similar technologies

The website may use cookies, local browser storage, identifiers, and similar technologies to maintain sessions, support login flows, preserve preferences, protect account access, measure usage, and support service reliability. Disabling those mechanisms may affect how certain workflows operate or whether some account-linked features function correctly.

Retention

SentinelLolge may retain personal information for as long as reasonably necessary to provide the service, maintain account relationships, resolve disputes, enforce terms, preserve security records, comply with law, and maintain appropriate business and operational records. Different categories of information may be retained for different periods depending on their purpose and the obligations attached to them.

Security

SentinelLolge applies technical and organizational measures intended to protect personal information against unauthorized access, misuse, loss, or disclosure. No internet-connected or browser-based environment can be made completely risk-free.

Your choices and requests

Subject to applicable law and the nature of the relationship, you may have rights to access, correct, delete, export, object to, or restrict certain processing of personal information. SentinelLolge may need to verify a request and may decline or limit a request where permitted by law, where the request affects the rights of others, or where the information must be retained for security, legal, or operational reasons.

International use and updates

The website service may be used across jurisdictions, and personal information may be handled in countries other than the one from which you access the service, subject to applicable legal requirements. SentinelLolge may update this policy from time to time to reflect changes in the service, legal requirements, or operational practices. The updated version becomes effective when published unless a different date is stated.

Contact

Questions, requests, or complaints relating to this policy may be directed through the contact details on the contact page.

Terms

Terms of use for the current website service.

These terms govern access to and use of the current SentinelLolge website service. Applies to the public website service. Separate business terms apply only where agreed in writing. Effective date: May 7, 2026.

Service scope

SentinelLolge currently offers a browser-based service for file protection, controlled sharing workflows, and related account-linked features. References to future plans, organization workflows, or expanded packaging are informational only unless they are expressly made available through a live purchasing or contracting path.

Eligibility and account use

You are responsible for ensuring that your use of the service is lawful and appropriate for your circumstances. If the service requires an account for a given workflow, you must provide current and accurate account information and keep your credentials secure. You are responsible for activity carried out through your account unless the activity results from SentinelLolge's own fault or an unauthorized compromise outside your reasonable control.

Permitted use and customer responsibilities

You may use the service only for lawful purposes and only in relation to content and workflows you are entitled to handle. You remain responsible for the files you protect, the recipients with whom you share them, the passwords or access material you create, and any confidentiality, employment, privacy, export-control, consumer-protection, or sector-specific obligations that apply to your own use case.

Compatibility and operational limits

The service is designed for modern browser environments, but identical behavior is not guaranteed across all devices, browsers, operating systems, network conditions, or local security settings. Preview behavior, local file handling, media rendering, and large-file performance may vary. For a sensitive, business-critical, or time-dependent workflow, test on the intended recipient environment before relying on it.

Security model and practical limits

SentinelLolge is designed to improve confidentiality and control, but no browser-delivered or account-linked system can eliminate all security risk. Different workflows rely on different trust assumptions. Assess whether the service is appropriate for your own risk model rather than treating any feature description as a guarantee against every recipient-side, browser-side, or endpoint-side threat.

Availability, changes, and suspension

SentinelLolge may modify, suspend, limit, or discontinue features where reasonably necessary for product development, legal compliance, abuse prevention, security, commercial changes, or operational reasons. SentinelLolge may also suspend access where reasonably necessary to investigate misuse, protect the service, comply with legal obligations, or limit harm to users or third parties.

Fees, paid access, and renewals

Where paid plans or paid features are offered through a live checkout flow, the pricing, billing cadence, taxes, and renewal terms shown at the time of purchase form part of the transaction. Unless the live billing flow states otherwise, paid access is provided for the purchased term and renewals, if any, are governed by the cancellation and billing information presented in that live flow or in the relevant account billing surface.

GateSeal retention and plan limits

Account-linked GateSeal availability, storage limits, retention windows, and permanent-entry options vary by plan and may change if the live product surface is updated. On the current Base plan, GateSeal entries are time-limited and currently expire 30 days after creation. Base-plan GateSeal entries are not permanent, may become unavailable automatically once expired, and may be removed during normal service cleanup after expiry.

Refunds and mandatory consumer rights

Except where required by applicable law, fees are non-refundable once paid. Nothing in these terms excludes any non-waivable consumer right or statutory remedy that applies under governing law. If a separate refund or cancellation policy is published, it forms part of the overall purchase framework together with these terms and the disclosures shown in the live purchase flow.

Intellectual property and service materials

SentinelLolge retains all rights in the service, including the website, branding, interface elements, and service materials, except for rights in customer content that remain with the applicable user or rights holder. These terms do not transfer ownership of the service or create any implied license beyond the limited right to use the service in accordance with these terms.

Customer content and legal compliance

You represent that you have the necessary rights to use, process, share, and protect the content you place into the service. SentinelLolge does not assume responsibility for the legality, accuracy, or underlying rights status of customer content. Nothing in the service constitutes legal advice on how regulated, proprietary, confidential, or personal information may lawfully be handled.

Limitation of assurances

To the maximum extent permitted by applicable law, the service is provided on an as-available basis and SentinelLolge does not promise uninterrupted operation, universal compatibility, or suitability for every purpose. Nothing in this section excludes liability that cannot lawfully be excluded or limited.

Contact

Questions about these terms, notices concerning the website service, and requests relating to legal or billing matters may be sent using the contact details on the contact page.

Refund policy

Refund and cancellation policy.

This policy sets out the refund and cancellation position for the current website service. Applies to live paid purchases of the current website service. Mandatory legal rights continue to apply. Effective date: May 7, 2026.

Scope

This policy applies to paid purchases made through a live SentinelLolge checkout flow for the website service. It does not convert non-live demonstrations, indicative pricing, development-only billing paths, or internal test flows into completed consumer transactions.

General rule

Except where required by applicable law, fees are non-refundable once paid. Where the service provides digital access or digital features promptly after purchase, change-of-mind refunds are generally not offered after that access has started.

Consumer rights preserved

Nothing in this policy limits any statutory remedy or non-waivable consumer right that applies under governing law. That includes rights that may arise where the service is not provided, is materially defective or deficient, is materially not as described at the time of purchase, is billed in error, or is subject to a mandatory cancellation, withdrawal, or cooling-off right.

Immediate access and cancellation rights

If immediate access to digital services is provided after purchase, any otherwise applicable cancellation or withdrawal right may be limited only where the live checkout flow captures the consent and acknowledgements required by applicable law. If those disclosures are not properly presented, SentinelLolge does not assume that any such right has been waived.

Cancellation and renewals

Where recurring billing is enabled, the cancellation and renewal terms shown in the live checkout flow or account billing surface govern how future renewals stop. Unless the applicable billing flow states otherwise, cancellation prevents future renewal and does not ordinarily reverse access already provided for the current paid term.

Billing errors

If a transaction is duplicated, billed incorrectly, or associated with the wrong account or plan state, SentinelLolge may investigate and, where appropriate, correct the billing outcome or work with the relevant payment environment to address the issue. SentinelLolge may request enough information to verify the transaction and the account involved before taking action.

Requests and review

Refund, billing, and cancellation requests should be sent using the contact details on the contact page. To support review, provide the account identifier or email used for the purchase, the transaction date, the amount charged, and a concise explanation of the issue.

Security overview

Security overview for the current website service.

This overview states the current security position of the SentinelLolge website service. Informational only. Not a warranty, audit report, or certification statement. Effective date: May 7, 2026.

General security approach

SentinelLolge applies technical and organizational measures intended to support confidentiality, integrity, and controlled access in the ordinary operation of the website service. The service uses a browser-first protection model together with account-linked controls for certain workflows. The protection boundary depends on the feature used and the environment in which that feature is used.

Standard file-protection workflows

In the standard website workflow, protected file handling is designed to occur within the browser rather than by routinely transmitting raw source file contents into the service for ordinary storage. That architecture reduces certain categories of hosted-content exposure, but it does not eliminate all operational, browser, endpoint, or recipient-side risk.

Managed access-control workflows

Some workflows rely on service-side account, access-control, or enforcement mechanisms in addition to local browser processing. Those workflows provide stronger control than a purely self-contained export, but they do not guarantee prevention of every hostile recipient action, compromised endpoint, or local manipulation scenario.

Account security

Authenticated features may use account, session, and access-management controls intended to reduce unauthorized use and maintain service integrity. Those controls support account discipline but do not replace the need for strong credentials, careful device hygiene, and sound customer-side security practices.

Operational limits

Security outcomes depend in part on browser behavior, device integrity, recipient conduct, network conditions, and the way a customer chooses to use the service. No online service can guarantee uninterrupted operation, universal compatibility, or absolute protection against every misuse, attack, disclosure, or failure scenario.

No public certification claim

No certification, audit standard, or independent assurance is claimed unless SentinelLolge expressly publishes it.

Security contact

Security-related questions or responsible disclosure communications may be directed through the contact details on the contact page.

Data processing addendum

Data processing addendum summary.

This summary outlines the data processing framework SentinelLolge may offer to business customers for the website service. Applies only where SentinelLolge and a customer agree in writing to business processing terms. Effective date: May 7, 2026.

When this addendum applies

This summary is not a standalone contract and does not bind either party absent a written agreement. It reflects the type of processing terms that may be incorporated into a business arrangement.

Roles of the parties

Where a business customer uses SentinelLolge to process personal data on that customer's behalf, the customer is generally expected to act as the controller and SentinelLolge as the processor for the applicable customer-controlled processing. SentinelLolge may nevertheless act as an independent controller for its own corporate records, service security, fraud prevention, billing administration, legal compliance, and similar internal purposes.

Scope of processing

The applicable business agreement should describe the subject matter, duration, nature, and purpose of processing, together with the categories of personal data and data subjects relevant to the contracted use case. The current website service is not designed around routine hosted ingestion of every raw source file used in standard browser-first protection flows, but it may process account, access-control, billing, support, and related operational information as part of providing the service.

Instructions, retention, and deletion

SentinelLolge processes customer-controlled data only in accordance with the applicable agreement, documented customer instructions, service operation requirements, and applicable law. Retention, deletion, return, and backup handling commitments are governed by the executed agreement.

Security measures

Where a written business arrangement is in place, SentinelLolge may commit to commercially reasonable technical and organizational measures appropriate to the service and the agreed processing scope. This summary is not a public audit statement, enterprise security schedule, or guarantee of a particular control framework.

Subprocessors and transfers

Where SentinelLolge uses third-party providers to support the service, the applicable business arrangement may address subprocessor use, notice expectations, and any transfer-related requirements necessary for the customer's legal review. Public-facing legal pages should not be treated as the sole source of negotiated transfer or audit terms for business use.

Incidents, assistance, and contact

Incident notification, data subject assistance, audit support, and regulatory cooperation commitments are governed by the executed business agreement. Questions about business processing terms may be directed through the contact details on the contact page.

Subprocessors

Subprocessor disclosure approach.

SentinelLolge may use subprocessors to support operation of the current website service. Public disclosure is provided at a legal and operational level. Additional diligence materials may be handled separately where appropriate. Effective date: May 7, 2026.

General approach

SentinelLolge may use third parties to support hosting, service operation, analytics, identity, payment processing, communications, and related business functions.

Public disclosure scope

The public disclosure does not enumerate every downstream supplier, infrastructure dependency, or internal tool. It states the legal and operational scope within which subprocessors may support the website service and may handle personal information relevant to their role.

Categories of subprocessor activity

Subprocessors, where used, may support account operation, identity and sign-in flows, analytics and measurement, payment processing, customer communications, customer support operations, hosting and storage, security monitoring, and related operational functions necessary to run the service responsibly.

Business diligence

Where a customer requires a more detailed subprocessor review in connection with a genuine business relationship, SentinelLolge may provide additional diligence information through the appropriate commercial or legal process.

Updates

SentinelLolge may update this page as the service evolves, as legal requirements change, or as the company's disclosure posture changes. The absence of a public vendor-by-vendor register does not mean the service operates without subprocessors.

Relationship to other documents

Read this page together with the privacy policy, security overview, and any separately agreed business terms. Requests relating to data processing, diligence, or subprocessor concerns may be directed through the contact details on the contact page.
