Effective date: 13 March 2026

Version: 2.4

§1. Definitions

The terms used in these Terms of Service shall have the following meanings:

• Service Provider / We – Tomstack Tomasz Turek, with its registered address at: ul. Szkolna 2K, 42-512 Preczów, Poland, Tax Identification Number (NIP): 6010041104,
• User – a natural person (min. 18 years of age) or a legal entity holding an account on the Platform.

• Review – a workspace containing one or more files (STEP, PDF, image) together with associated comments and pins.
• Organisation – an entity (company or team) managing multiple Users and Reviews under a single collective account.
• Content – all files, comments, pins, and other materials uploaded or created by the User on the Platform.
• Plan – the package of features and limits selected by the User: Starter (free), Pro, or Team.
• Service / Platform – the platform available at revievv.io and app.revievv.io.
• Promotion – a time-limited special offer (discount code, trial, early-bird, etc.) subject to the terms set out in §4.6.

§2. General Provisions

These Terms of Service set out the rules for using the revievv.io Platform. By using the Platform, the User accepts these Terms in full.

The Platform is intended for professional entities (B2B) and persons conducting professional or creative activity.

Paid Plans for business entities only: Paid Plans (Pro, Team) are available exclusively to business entities. By purchasing a Paid Plan, the User confirms they are acting as a business entity, which is verified by the mandatory provision of a VAT identification number (NIP / VAT ID).

Using the Platform requires a device with an up-to-date web browser supporting WebGL (for 3D models) and an internet connection.

§3. Registration and User Account

Account registration is free of charge. Registration requires providing a valid email address and creating a password.

The User is obliged to:

• Provide truthful data upon registration;
• Keep login credentials confidential;
• Immediately notify us of any unauthorised access to the account at: [email protected].

One account may be assigned to one natural person. Sharing login credentials with third parties is prohibited (team management is handled through the Organisation mechanism).

§4. Plans, Payments, and Billing

4.1 Starter Plan (Free)

New accounts use the Starter Plan by default, free of charge, with the following limits:

• Active Reviews: 3
• 3D CAD conversions: 2 / month
• PDF and image Reviews: unlimited
• Storage: 500 MB
• Reviewers / commenters: unlimited

Starter Plan limits may be changed subject to an appropriate notice period (§11).

A single User (identified by email address) may own only one Organisation on the Starter Plan. Creating multiple free Organisations by the same User is prohibited. This restriction does not apply to Organisations on Paid Plans — a User may own any number of Organisations on Paid Plans.

4.2 Paid Plans

Available Paid Plans and their limits:

• Pro: €19/mo (monthly billing) or €15/mo (annual billing). Limits: 15 active Reviews, 10 3D CAD conversions/mo, unlimited PDF & image Reviews, 5 GB storage, unlimited reviewers.
• Team: €49/mo (monthly billing) or €39/mo (annual billing). Limits: 50 active Reviews, 50 3D CAD conversions/mo, unlimited PDF & image Reviews, 50 GB storage, unlimited reviewers.

Paid Plans are available exclusively to business entities. A valid VAT identification number (NIP / VAT ID) is required to complete the purchase.

The current pricing is always available at: revievv.io/en#pricing.

Payments are processed by: Stripe, LLC (formerly Stripe, Inc.; converted on 3 January 2026). In the EMEA region, transactions are processed by Stripe Payments Europe, Limited (SPEL), registered in Ireland.

A VAT invoice is issued based on the data provided at the time of purchase.

Structured (e-)invoices (KSeF): Since 1 February 2026, B2B VAT invoices within the territory of Poland are issued as structured invoices via the National e-Invoicing System (KSeF). An invoice is deemed delivered upon assignment of its identifying number in KSeF. The invoice visualisation available in the application dashboard is for informational purposes only and does not constitute an invoice within the meaning of tax law. The obligation to use KSeF is being introduced in phases: from 1 February 2026 for large taxpayers (revenue exceeding PLN 200 million), from 1 April 2026 for other active VAT payers, and from 1 January 2027 for micro-entrepreneurs. B2C invoices are not subject to the KSeF obligation.

The subscription is billed on a recurring basis (monthly or annually, depending on the selected variant) and is automatically renewed at the beginning of each billing period.

4.3 Subscription Cancellation

The User may cancel the subscription at any time in the account settings (Subscription → Cancel plan). Cancellation takes effect from the next billing period — until the end of the paid period, the User retains full access to Paid Plan features.

After the paid period ends, the account automatically reverts to the Starter Plan. Files exceeding the Free Plan limits may be locked for download — the User will be notified of this 14 days in advance by email.

Deleting the account (§12.1) is equivalent to immediate cancellation of the subscription without the right to a refund for the unused period.

4.4 Refunds

A refund is available within 14 days of the date of the first charge in a given billing cycle, provided that the User has not actively used Paid Plan features during that period (i.e., has not uploaded new files or created new Reviews).

To submit a refund request:

• Send an email to: [email protected] with the subject "Refund request – [account email]";
• Provide the reason for cancellation and the transaction number (available in the payment history in the account settings).

The request will be processed within 5 business days. The refund is issued to the payment method used at the time of purchase (card refund time: typically 5–10 business days on the bank's side).

Refunds are not available: for periods covered by a Promotion (unless the Promotion terms provide otherwise), or in the event of account suspension or deletion due to a breach of these Terms.

revievv.io does not sell physical goods — the physical goods return policy does not apply.

4.5 Billing Disputes

If you believe you have been charged incorrectly, please contact [email protected] first before initiating a chargeback with your payment provider. We commit to responding to and resolving justified billing disputes within 10 business days.

Unjustified chargebacks (in cases where the service was provided in accordance with these Terms) may result in temporary suspension of the account pending resolution.

4.6 Promotions and Special Offers

The Service Provider may organise Promotions (discount codes, trial periods, early-bird offers, partner programmes, etc.). Each Promotion is subject to the following general terms:

• A Promotion is valid only within the period specified in its specific terms;
• Each User may use a given Promotion only once, unless the specific terms provide otherwise;
• Promotions may not be combined with each other or with other discounts, unless expressly stated otherwise;
• The discount applies only to the first billing period; after its expiry, the standard Plan price is charged;
• The Service Provider reserves the right to modify or terminate a Promotion at any time, without affecting the rights of Users who have already used it;
• Discount codes are single-use and may not be exchanged for cash;
• Trial period: after its conclusion, the account automatically reverts to the Free Plan or the selected Paid Plan — the User will be notified in advance.

§5. Rules of Using the Service — Permitted Use

The User may use the Platform only for purposes consistent with the law and with these Terms of Service, in particular for:

• Uploading own files in order to obtain feedback from clients, collaborators, or reviewers;
• Organising and managing the design review process;
• Sharing Reviews with external reviewers via links.

§5a. User Representations and Warranties

By uploading Content to the Platform and using its features, the User represents and warrants that:

• The User holds all necessary rights, licences, and authorisations to the uploaded Content, including copyright, industrial property rights, and consents of rights holders;
• To the extent that uploaded Content contains personal data of third parties, the User — as the Data Controller of such data within the meaning of the GDPR — has a valid legal basis for processing and has fulfilled information obligations towards those persons;
• The uploaded Content does not infringe intellectual property rights, personal rights, trade secrets, or other rights of third parties;
• The uploaded Content is not subject to export restrictions requiring additional permits that the User does not hold;
• The User will not use the Platform in a manner that violates applicable law;
• All information provided upon account registration and in Organisation settings is truthful, up to date, and complete.

The representations are made at the time of each upload of Content and remain in force for the entire period of its storage.

Making false representations constitutes a material breach of these Terms entitling the Service Provider to immediately suspend or delete the account (§12.2) and to pursue claims in accordance with §10a.

§6. Prohibited Content

It is prohibited to upload, store, or share through the Platform content that:

• Infringes copyright, patents, trademarks, or other intellectual property rights of third parties;
• Contains viruses, malware, or code that may disrupt the operation of the Platform;
• Contains illegal, offensive, pornographic, or hate-inciting content;
• Constitutes confidential information or trade secrets without the owner's consent;
• Is subject to export sanctions or other legal restrictions (see §6a).

We reserve the right to remove content that breaches these Terms and to suspend or delete accounts without prior notice in the event of serious violations.

§6a. Legal and Export Restrictions

The revievv.io Platform is made available only to Users acting in compliance with applicable law. Use of the Platform is prohibited for:

• Persons or entities listed on EU, US (OFAC SDN), UN, or other relevant sanctions lists;
• In countries or territories subject to comprehensive EU or US sanctions;
• For transmitting files subject to export controls without the required permits.

Responsibility for compliance with export regulations rests solely with the User. In the event of a reasonable suspicion of a violation, the Service Provider reserves the right to immediately suspend the account and notify the relevant authorities.

§6b. IP Infringement Reporting Procedure (Notice-and-Takedown)

No monitoring obligation: The Service Provider does not monitor, scan, analyse, or evaluate the content of files uploaded by Users. The Platform functions as a hosting platform enabling the storage, conversion, and sharing of Content solely at the User's instruction.

Infringement report: Any person who believes that Content posted on the Platform infringes their IP rights may submit a report to [email protected] containing: the reporter's contact details, identification of the Content (URL/Review identifier), identification of the infringed right, and a good-faith declaration.

Actions: Upon receipt of a complete report, the Service Provider will promptly (within 3 business days): temporarily block access to the indicated Content, notify the User, and enable a counter-notification (10 business days). If the reporter does not file a lawsuit within 14 days of the counter-notification, the Content will be unblocked.

No dispute resolution: The Service Provider is not a party to the dispute and acts solely as a technical intermediary.

§7. Intellectual Property and Content Licence

7.1 Ownership of User Content

All files and materials uploaded by the User remain the User's exclusive property. The Service Provider does not acquire any ownership rights to the Content.

7.2 Technical Licence

By uploading Content to the Platform, the User grants the Service Provider a non-exclusive, royalty-free licence to store, display, convert (e.g., STEP to glTF), and deliver such Content solely for the purpose of providing the service. The licence expires automatically upon deletion of the Content or the account.

3D preview on the Platform: File conversion (e.g., STEP to glTF/GLB) is performed automatically to enable preview in the browser. Due to the conversion technology used, minor geometric deviations and simplifications in the model visualisation compared to the source file may occur. The 3D preview is intended for review and communication purposes (comments, pins, discussion) and does not replace verification in dedicated CAD software. The source file remains available for download in its original form.

7.3 Platform Intellectual Property

The Platform, its code, interface, logo, graphics, and documentation are the property of the Service Provider and are protected by copyright. Their copying, modification, or distribution without written consent is prohibited.

§8. Personal Data Processing (Processor Role)

To the extent that the User (as the Data Controller — Art. 4(7) GDPR) processes personal data of third parties using the Platform, the Service Provider acts as the Data Processor (Art. 4(8) GDPR).

By accepting these Terms, the User enters into a Data Processing Agreement (DPA) with the Service Provider on the terms set out in §15 below.

§9. Platform Availability

We make every effort to keep the Platform available 24/7. Scheduled maintenance windows will be communicated at least 24 hours in advance.

We do not guarantee a specific level of availability (SLA). We are not liable for interruptions resulting from third-party infrastructure failures or force majeure events.

Review expiration: The User may set an expiration date for a Review. After that date, access to the Review is automatically blocked for all Reviewers. Files remain available to the User (owner) until manually deleted. Responsibility for correctly setting the expiration date rests with the User.

No archival function: The Platform does not constitute an archival, backup, or long-term data storage system. The User is solely responsible for maintaining their own backups of all files uploaded to the Platform.

Force majeure: The Service Provider shall not be liable for failure to perform the service caused by circumstances beyond its reasonable control, including: natural disasters, cyber attacks (DDoS, ransomware), failures of third-party providers (Hetzner, Cloudflare, Stripe, Resend), government orders requiring suspension of the service, internet connectivity disruptions, and legislative changes preventing the provision of the service. In the event of force majeure, the Service Provider will promptly inform Users of the situation.

§10. Limitation of Liability

To the maximum extent permitted by law:

• The Service Provider shall not be liable for content uploaded by Users;
• The Service Provider shall not be liable for data loss resulting from the User's actions;
• The Service Provider's aggregate liability is limited to the amount of fees actually paid by the User in the preceding 12 months.

The above limitations do not exclude liability in cases where mandatory provisions of law do not permit such exclusion.

No Content monitoring: The Service Provider does not monitor, scan, or analyse the content of files and is not liable for infringements of third-party rights arising from Content uploaded by the User.

Responsibility for access settings: The User bears sole responsibility for the configuration of access settings for their Reviews, including: the choice between public and restricted access, management of the Reviewer list, expiration dates, and sharing links with third parties.

§10a. Indemnification

The User agrees to indemnify and hold the Service Provider harmless from liability and to cover reasonable costs (including legal costs) arising from third-party claims caused by:

• Breach of the representations set out in §5a;
• Uploading Content that infringes the rights of third parties;
• Processing personal data without a valid legal basis;
• Breach of export or sanctions regulations;
• Using the Platform in breach of these Terms.

The Service Provider will promptly notify the User of any claim and allow participation in the defence. This clause survives termination of the contract.

§11. Changes to the Terms

We reserve the right to amend these Terms. We will notify you of changes by email or by an in-app notification at least 30 days in advance.

If you do not accept the new terms, you may delete your account before the date the changes take effect. Continued use of the Platform after that date constitutes acceptance of the new Terms.

§12. Contract Termination and Account Deletion

12.1 By the User

The User may delete their account at any time in the application settings. Deletion results in the permanent removal of all data and files in accordance with the Privacy Policy.

Data export: Before deleting the account, the User may download their Content using the export function (account settings) or by contacting [email protected]. Data is provided in ZIP format (original files + JSON metadata).

12.2 By the Service Provider

• Breach of the provisions of these Terms (including the representations set out in §5a);
• Acting to the detriment of the Platform or other Users;

• Account inactivity for more than 24 months (Starter Plan — with prior notification by email).
