Terms of Service

1. Acceptance

By using helvety.com, helvety.cloud, or any Helvety product that links to these Terms ("the Services"), you agree to these Terms and our Privacy Policy. If you do not agree, do not use the Services. Helvety by Rubin is the provider. For Helvety Cloud, creating an account or accepting these Terms in the product also binds you to the Acceptable Use section, the E2EE / zero-access notice, and the Billing section below.

2. Products

Current Helvety offerings include:

• Helvety PDF, Helvety Image Editor, and Helvety OCR: browser tools on helvety.com that process files on your device under the current architecture.
• Helvety Store: catalog and public downloads (for example Helvety SPO Explorer packages).
• Power Platform Configurator: Choose classic or new designer for Power Automate flow/run URLs. Control survey flags. Reveal or enable Power Apps form elements. Power Automate: choose Classic Designer, New Designer, or Paused; Hide sets v3survey=false on rewrites, while Show only normalizes an existing parameter. Power Apps: reveal hidden tabs, sections, and controls or enable disabled controls on supported model-driven record forms. Distributed via the Chrome Web Store.
• Helvety SPO Explorer and Helvety Screen Tools: Microsoft 365 and Windows products distributed separately from the browser tools above.
• Helvety Cloud (helvety.cloud): passwordless, end-to-end encrypted workspace service with email one-time-code sign-in, device unlock via WebAuthn PRF / passkey, and optional paid plans via Stripe.

Public tools and Store listings are currently offered free of charge. Helvety Cloud has a free plan and paid options described under Billing. Features may change or be withdrawn. Enterprise add-ins and extensions you install into Microsoft 365 or a browser follow the host platform's rules in addition to these Terms.

3. Geographic Eligibility

The Services are primarily intended for customers in Switzerland. We do not offer the Services to persons or entities located in the European Union or the European Economic Area (EU/EEA). You must not use the Services if you are located in the EU/EEA, or on behalf of a person or entity located there.

When Helvety Cloud requires acknowledgment of this section, you warrant that you are not located in the EU/EEA and are not using the Service on behalf of a person or entity located there. Helvety may refuse, suspend, or terminate access if it reasonably believes this warranty is false or that continued use would place Helvety under obligations it does not intend to assume.

4. Access and Availability

Product Access Characteristics

• Helvety PDF never asks you to log in for routine PDF edits.
• Helvety Image Editor does not require login for the standard annotation flow.
• Helvety OCR does not require login for the standard text-extraction flow.
• Helvety Store catalog browsing and public downloads do not require a Helvety account.
• Helvety Cloud requires an email account for one-time-code sign-in and a separate unlock passkey for encryption. Session sign-in is not the same as encryption unlock.

Product Access and Availability: We aim for reliable uptime but do not guarantee uninterrupted or error-free service. Maintenance, outages, rate limits, and third-party platform changes (Microsoft, Google Chrome Web Store, hosting, GitHub Releases, Supabase, Stripe) may affect access.

5. Acceptable Use

You may use the Services only for lawful purposes. You must not:

• Probe, overload, or disrupt our infrastructure or downloads
• Circumvent rate limits, account limits, or security controls
• Use the Services to distribute malware, spam, or infringe others' rights
• Misrepresent affiliation with Helvety or misuse Helvety trademarks
• Use Helvety Cloud for illegal activity, including storage or distribution of illegal content, child sexual abuse material, prohibited terrorism content, harassment, fraud, or unauthorized access to systems
• Scrape or harvest Helvety Cloud accounts without authorization, or probe systems except through coordinated responsible disclosure to Helvety

Because Helvety Cloud data is end-to-end encrypted, Helvety cannot moderate plaintext. Enforcement options are limited to account-level and ciphertext-level measures (for example suspending accounts, deleting encrypted blobs or workspaces, or blocking access) based on signals Helvety can see, such as abuse of APIs, illegal account activity, or lawful requests relating to metadata Helvety holds. Helvety does not claim the ability to inspect or "clean" encrypted content.

You are responsible for the lawfulness of content you process or encrypt and for compliance with applicable law. Helvety's inability to read Cloud data does not authorize illegal use. If Helvety reasonably believes your use creates legal risk or harms the Service or others, Helvety may suspend or terminate access without prior notice when urgency reasonably requires it. Abuse reports: Impressum (Abuse) or contact@helvety.com.

6. Your Content and Local Tools

6.1 Your files

You remain responsible for files and content you open in Helvety PDF, Helvety Image Editor, Helvety OCR, Screen Tools, or similar local software. You confirm you have the rights to process that content.

6.2 License to Us

Under the current architecture, Helvety PDF, Helvety Image Editor, and Helvety OCR keep PDF contents, or extracted text, and images on your device for routine processing. You do not grant us a license to use that local content for our own products or AI training. If you email us attachments or text for support, you grant us a limited license to use that material only to respond and improve support quality. For Helvety Cloud, you retain ownership of content you create and grant Helvety only the rights needed to store and transmit ciphertext and related metadata to operate the Service.

6.3 Your Responsibilities

Keep backups of important PDFs and images. Verify extracted text and edited exports before relying on them. Local tools can fail or lose unsaved work if the browser tab closes. For Helvety Cloud, keep control of your email, unlock passkey, devices, and any recovery export. Helvety cannot reset encryption access for you.

7. Helvety Cloud and E2EE / Zero-Access Notice

This section is a core part of how Helvety Cloud works. You must acknowledge it before encryption setup in the product.

Helvety cannot decrypt your data. There is no company master key, no key escrow, and no support workflow that restores encrypted plaintext. Authentication (email OTP for session) is separate from encryption unlock. A signed-in session does not mean Helvety can read encrypted workspace data.

If you lose your unlock passkey / PRF capability and any recovery export you were shown, Helvety cannot recover your data. Lost keys mean permanent loss of that encrypted content. Any recovery export shown during setup must be stored offline by you. Never email it to Helvety or paste it into support channels with an expectation of restoration.

Encrypted content lives in workspaces. Every invited member has the same rights: invite others, remove members, manage billing, and delete the workspace. Only invite people you trust fully. Leaving a shared workspace, or being removed, drops your membership and wrapped keys for that workspace. Content stays for remaining members. Helvety does not rotate workspace keys when someone leaves or is removed. If you are the only member and leave, or if any member deletes the workspace, its ciphertext is permanently deleted for everyone. Your Personal workspace cannot be left or deleted except by deleting your account. Deleting your account permanently removes your account data and workspaces where you are the only member. Shared workspaces remain for other members.

By accepting this notice you confirm that you understand Helvety cannot read or restore your data, that you are responsible for your content and keys, and that permanent data loss is possible if unlock or recovery material is lost. Helvety Cloud is not a plaintext backup, not a key-recovery service, and not a content host that can inspect or restore your encrypted workspace content. Support cannot decrypt your data or restore lost keys.

8. Billing

This section applies to Helvety Cloud. Public tools and Store listings that are free remain free unless we state otherwise for a specific paid product.

Helvety Cloud offers a free plan and a paid Pro Workspace plan per workspace, processed through Stripe, plus an optional Capacity Increase add-on that raises paid limits together. Nothing is charged unless a workspace member explicitly starts Checkout (where the price is shown before any charge) or changes paid add-ons. Any discounts are applied through Stripe. Helvety does not issue separate in-app discount or complimentary codes. These terms do not themselves create an obligation to purchase.

The free plan applies fair-use limits per workspace. File uploads and document storage are not available on the free plan. Current limits are shown in the product where they apply. Each account may have one free-tier workspace attributed to it (typically the Personal workspace). Additional workspaces attributed to the account require Pro Workspace access for that workspace. If a paid Pro Workspace ends and you would then own more than one free-tier workspace, Helvety may soft-lock the overflow workspace(s): existing encrypted content stays available to open, edit, download, export, and delete, but creating new resources in that workspace is paused until you upgrade or reduce owned free workspaces. Helvety does not delete ciphertext or withhold wrapped keys solely because a workspace is soft-locked.

Subscriptions are workspace-scoped: any member may manage that workspace's Pro Workspace plan and add-ons. Leaving a Pro workspace does not cancel billing. Pro Workspace includes higher operational limits and encrypted file and document storage for that workspace, within limits shown in the product. Uploaded files are end-to-end encrypted on your device; Helvety stores ciphertext and operational size meters only. Capacity Increase requires an active Pro Workspace subscription. Prices, billing intervals, renewals, taxes, and any Stripe-applied discount are shown at Stripe Checkout or in the billing portal. Unless stated otherwise, subscriptions renew automatically until cancelled. You may cancel renewal at any time in the Stripe billing portal; access to paid limits continues through the paid period already purchased unless stated otherwise. Helvety never needs encrypted plaintext or raw encryption keys for billing.

If mandatory consumer law grants you a withdrawal right for digital services, Helvety will honor that right as required. If a paid plan is active and payment fails, Helvety may retry charges and may end paid entitlements after notice so free-plan limits apply. Billing questions: contact@helvety.com.

9. Intellectual Property and Source

Helvety branding and product names are used as trademarks by Helvety by Rubin. The helvety.com monorepo source is licensed under the GNU Affero General Public License version 3 (AGPL-3.0) or later. Other Helvety repositories may use different licenses, including MIT. Always check the repository LICENSE file or release source link for the package you obtain. Chrome Web Store listings and Microsoft 365 packages remain subject to those platforms' policies. Subject to these Terms and Acceptable Use, Helvety grants you a limited, non-exclusive, non-transferable, revocable right to use the Services for lawful purposes.

10. Disclaimers and Liability

The Services are provided "as is" and "as available," without warranties of any kind to the fullest extent permitted by Swiss law. We do not warrant fitness for a particular purpose, merchantability, non-infringement, or that results (including OCR text or PDF edits) will be accurate or complete. Helvety does not warrant that encrypted Helvety Cloud data will remain recoverable if you lose unlock or recovery material, or that third-party browsers, OS passkey stores, or devices will always remain compatible.

To the fullest extent permitted by law, Helvety by Rubin and Caspar Camille Rubin (as sole proprietor) are not liable for indirect, incidental, special, consequential, or punitive damages, or loss of data, profits, revenue, goodwill, or business, arising from use of the Services, including permanent loss of Helvety Cloud data due to lost keys or recovery material. Our aggregate liability for claims relating to the Services is limited to CHF 0 for free offerings, or the greater of CHF 100 or the amounts you paid Helvety for the Service in the twelve (12) months before the claim. Nothing excludes liability that cannot be limited under mandatory Swiss law (or other mandatory consumer protections that apply to you), including liability for death or personal injury caused by negligence where such limitation is prohibited, or for fraud or willful misconduct.

You will defend and indemnify Helvety against claims, damages, and reasonable costs arising from your unlawful use of the Services, your encrypted content, or your breach of these Terms, except to the extent caused by Helvety's willful misconduct.

11. Governing Law

These Terms are governed by the substantive laws of Switzerland, excluding conflict-of-law rules. Exclusive jurisdiction is Basel-Stadt, Switzerland, except where mandatory law provides otherwise. Mandatory consumer rights that cannot be waived under applicable law remain unaffected. We do not offer the Services in the EU/EEA (see Geographic Eligibility).

12. Changes

We may update these Terms by posting a revised version on this page. Continued use after the "Last reviewed" date means you accept the updated Terms for public tools. For Helvety Cloud, material changes may require acceptance of a new version string before continued use of encrypted features.
