2. Acceptance and professional use

Use of the App entails full, express and unconditional acceptance of these Terms, the Privacy Policy and the Cookie Policy. If the User does not accept the Terms, the User must immediately stop using the App, uninstall it and erase all local data.

The User declares to be of legal age, to have full legal capacity to enter into this agreement, and not to use the App as a consumer within the meaning of Italian Legislative Decree 206/2005 (or equivalent foreign consumer-protection law), but solely within their professional or business activity as an engineer, technical consultant, surveyor or safety practitioner.

The App is intended exclusively for professional users. The Owner does not market the App as entertainment or consumer-use software.

3. Subject matter and features

Iridai is a mobile application supporting the work of engineering consultants, technical surveyors and safety professionals specialised in:

• CE conformity verification of machinery (Machinery Directive 2006/42/EC, Italian Legislative Decree 17/2010);
• Workplace safety audits (Italian Legislative Decree 81/2008 and equivalent occupational-safety regulations);
• Maintenance and digitisation (Industry 4.0);
• Configurable specialist domains (chemical risk, electrical installations, ATEX, etc.).

Main features:

a) Photo acquisition from Ray-Ban Meta smart glasses (via Meta Wearables DAT SDK) or iPhone; b) AI analysis of images using third-party artificial-intelligence models (Anthropic, OpenAI, Google) or third-party open-source models (MLX-community); c) Inspection management with automatic generation of reports in PDF and Markdown — expressly qualified as unsigned working drafts having no legal or evidentiary value; d) Speech recognition for hands-free activation (wake word); e) Optional integrations with third-party services (Twilio SMS, n8n workflow, RAVENG portal).

4. Licence to use

RAVENG grants the User a non-exclusive, non-transferable, non-sublicensable, revocable and limited licence to use the App for personal and professional purposes solely on the User's iOS device, in accordance with these Terms.

The App is and remains the exclusive property of RAVENG. All intellectual-property rights (source code, design, "Iridai" and "RAVENG" trademarks, logo, textual contents, specialist prompts, v2 JSON output schema, regulatory tables integrated in the prompts) are protected by applicable laws, including by way of injunctive relief.

5. User obligations and prohibitions

The User undertakes to:

a) Use the App in compliance with Italian, EU and other applicable laws; b) Not to sublicense, distribute, sell, rent or transfer the App or its components to third parties; c) Not to perform reverse engineering, decompilation or disassembly of the code except within the strict limits of Article 64-quater of Italian Law 633/1941 (analogous to EU Directive 2009/24/EC, Art. 5(3)); d) Not to use the App for illegal, fraudulent or third-party-rights-infringing purposes; e) Not to use the camera or microphone to capture images or recordings in places or circumstances where this is forbidden by law or by the workplace regulations of the User's client (e.g. military zones, restricted areas, hospitals, sensitive infrastructures) or without the consent of recorded persons; f) Respect the acceptable-use policies of the chosen AI Provider; g) Not to use the App to produce defamatory, illegal, IP-infringing, discriminatory, offensive or harmful content; h) Disable optional integrations (Twilio, n8n, RAVENG) if not entitled to use them with the indicated recipients; i) Verify every AI Output before relying on it in deeds, expert reports, signed inspection records or decisions having consequences for third parties (see §7).

6. Costs: Iridai Pro subscription and third-party API keys

6.1 "Iridai Pro Monthly" auto-renewable subscription

Access to the App's AI features requires an auto-renewable subscription named Iridai Pro Monthly, distributed exclusively through the Apple App Store on the following terms:

a) Price: € 9.90 per month (or the equivalent in the User's local currency at the exchange rate applied by Apple), VAT included where applicable; b) Duration of each period: 1 (one) calendar month; c) Automatic renewal: the subscription renews automatically at the end of each period by charging the then-current price to the User's Apple ID, unless the User cancels at least 24 (twenty-four) hours before the end of the current period; d) Free trial: new eligible Users (at Apple's sole discretion) are offered a 3 (three) day free trial, at the end of which, unless cancelled, the subscription is automatically converted into the paid plan and the first renewal is charged. Any unused portion of the free trial is forfeited if the User purchases a subscription before the trial expires; e) Payment method: payment is made exclusively through the payment method linked to the User's Apple ID (credit card, PayPal, iTunes credit, Apple Pay) and is managed directly by Apple Distribution International Ltd. (or the Apple entity competent for the User's country). The Owner does not receive, store or process the User's payment data.

6.2 Management, cancellation and refunds

a) Management: the User may view, pause, change plan or cancel the subscription at any time from the iOS Settings app → [your Apple ID name] → Subscriptions; b) Cancellation: cancellation disables auto-renewal; the User retains access to Pro features until the natural expiry of the already-paid period; c) Refunds: refund requests are handled exclusively by Apple under the Apple Media Services Terms (https://www.apple.com/legal/internet-services/itunes/). The Owner has no power to refund the User directly or to interfere with Apple's refund policy. The User acknowledges that, under Article 59(m) of the Italian Consumer Code (D.Lgs. 206/2005) and Article 16(m) of EU Directive 2011/83/EU, the right of withdrawal may be excluded for digital content whose performance has begun with the consumer's express consent; d) Restore: a User who reinstalls the App or switches device may restore their active subscription via the "Restore Purchases" button available on the subscription screen and in the App settings.

6.3 Family Sharing

The Iridai Pro subscription is Family Sharing-enabled. The primary payer may share access to Pro features with their Family Group members (up to 5 members plus payer) by enabling the option in their Apple ID → Subscriptions settings.

6.4 Price increases

In compliance with Apple's policies, in the event of a price increase for the subscription the User will receive an Apple email notification at least 30 (thirty) days before renewal at the new price, with the option to reject the increase by cancelling the subscription. Continuation of the subscription after notification constitutes acceptance of the new price.

6.5 Third-party AI Provider API keys and integrations — separate costs

The Iridai Pro subscription DOES NOT include the costs of API calls to third-party AI Providers:

a) Use of cloud AI features requires the User's personal API key with the chosen AI Provider (Anthropic / OpenAI / Google Gemini / ElevenLabs / Perplexity). The costs of such API calls are borne in full by the User, according to the respective Provider's price list, and are in addition to the subscription price; b) Use of the local MLX AI model does not entail API costs but requires disk space (1.5 — 7 GB) and an iPhone with sufficient RAM; c) Optional integrations (Twilio, n8n, RAVENG portal) may entail separate costs borne by the User.

The Indemnified Parties are in no way responsible for unforeseen charges, billing problems, account suspensions or service limitations attributable to the AI Provider chosen by the User or to third-party integrations.

6.6 Access suspension on non-payment

In case of failed renewal payment (e.g. expired card, insufficient funds, locked Apple ID), Apple manages a "billing retry" period typically up to 16 days. During this period, the App may continue to provide access to Pro features at the Owner's discretion ("grace period"). Once the billing retry period expires without renewal, access to Pro features is suspended until payment is restored.

7. NATURE OF AI OUTPUT — ERRORS, HALLUCINATIONS, INACCURACIES (ESSENTIAL CLAUSE)

The User expressly acknowledges and accepts that:

7.1 Structural characteristics of AI models

The generative AI models (LLMs, VLMs) used by the App — whether cloud-hosted (Anthropic, OpenAI, Google) or local (MLX-community: SmolVLM, Qwen-VL, Phi-Vision, Llama Vision) — are probabilistic and non-deterministic systems. By their inherent technical nature they:

a) Generate errors, omissions, inaccuracies, "hallucinations" (information fabricated yet presented with apparent certainty), potentially significant or systematic — such behaviour is not a defect of the App but a well-known property of the underlying AI models at the time of the App's distribution;

b) May cite inaccurate, repealed, outdated, fabricated regulatory references, even if formulated in apparently authoritative technical language;

c) May estimate distances, dimensions, parameters, calibres, severity ratings, risk categories approximately, systematically erroneously, or in a wholly misleading way;

d) May incorrectly classify compliance or non-compliance against a directive, standard or regulation;

e) May confuse different professional contexts, applying regulations that are not pertinent to the actual case;

f) Produce potentially different outputs even given identical inputs, due to the stochastic nature of samplers;

g) Are not certified for use as expert reports, forensic evidence or regulatory submissions.

7.2 AI Output is not a qualified or signed deliverable

AI Output does not constitute and cannot be qualified as:

• An expert report, sworn affidavit, certification, CE conformity declaration, risk-assessment document (DVR), occupational-safety policy programme, sworn appraisal or court-appointed expert technical opinion;
• An act signed by a licensed engineer or qualified professional under applicable regulations;
• An official communication to competent authorities;
• A document of legal, evidentiary or public-record value;
• A substitute for the User's professional judgement.

The PDF and Markdown reports automatically generated by the App are provisional working drafts that integrally require:

a) Critical review of technical content by the User professional; b) Validation of contents under the User's professional responsibility; c) Handwritten or qualified digital signature (CAdES/PAdES) under applicable regulations; d) Retention and registration in accordance with corporate procedures and/or applicable law.

7.3 Automated Decision-Making (Art. 22 GDPR)

The App does not implement automated decision-making within the meaning of Article 22 GDPR: AI Output is solely a decision-support tool. Final decisions rest at all times with the User professional.

7.4 Model updates and versioning

The underlying AI models are subject to unilateral modification by their respective vendors (deprecation, retraining, prompt-template changes). The Owner does not guarantee continuity of model behaviour over time.

8. EXCLUSION OF WARRANTIES — APP DELIVERED "AS IS"

8.1 Comprehensive warranty exclusion

To the maximum extent permitted by applicable law, the App is provided "AS IS" and "AS AVAILABLE", without any express, implied, statutory or other warranty, including, by way of illustration and not limitation, the exclusion of warranties of:

a) Fitness for a particular purpose; b) Accuracy, completeness, currentness or up-to-date status of contents; c) Compliance with the technical or regulatory standards cited by the AI Output; d) Uninterrupted operation free of errors, bugs, crashes or malfunctions; e) Compatibility with all iPhone models, all iOS versions, all Meta Ray-Ban smart glasses or third-party Bluetooth accessories; f) Availability of AI Providers (Anthropic, OpenAI, Google) — which may suspend, modify or render unavailable their services unilaterally; g) Absolute security of local data — although appropriate technical measures (Keychain, iOS sandbox) are adopted, no system is impenetrable; h) The App's ability to meet the User's expectations or the specific requirements of the User's work; i) Non-infringement of third-party intellectual-property rights in AI processing of images supplied by the User.

8.2 Mandatory savings

In any case the following are not affected:

• The cases of wilful misconduct or gross negligence of the Owner (Italian Civil Code art. 1229, paragraph 1, which prohibits clauses excluding/limiting liability for wilful misconduct or gross negligence);
• The mandatory provisions of the Italian Consumer Code (Legislative Decree 206/2005), where the User qualifies as a consumer;
• Breach of data-security obligations under GDPR (Reg. EU 2016/679), the UK GDPR / Data Protection Act 2018, and the Italian Privacy Code.

9. LIMITATION OF LIABILITY AND ILLUSTRATIVE LIST OF EXCLUDED DAMAGES

9.1 Limitation of liability

To the maximum extent permitted by applicable law, the Indemnified Parties (RAVENG by CE4U S.r.l., Carlo Tenca personally, the domain raveng.it and their directors, members, employees, collaborators, consultants, suppliers and assigns) are in no way liable to the User or to third parties for damages, costs, losses, fines or claims — direct, indirect, incidental, consequential, exemplary, punitive, of an economic, reputational, professional, physical, moral or any other nature — arising, by way of illustration and not limitation, from:

a) Errors, omissions, hallucinations, inaccuracies, invented or outdated regulatory citations by the AI models used by the App, even if recurrent or systematic;

b) Delivery of inspection reports, surveys, expert reports, CE conformity declarations, DVR, technical documents that incorporate AI Output without proper verification and validation by the User or another qualified professional;

c) Third parties' reliance on the AI Output or on the reports generated by the App, including where such reliance was facilitated by the User;

d) Administrative, civil or criminal penalties imposed on the User or third parties as a result of using the App or its outputs;

f) Hardware damage: iPhone, Ray-Ban Meta smart glasses, AirPods, Bluetooth headphones, sensors, accessories — arising from installation, use, uninstallation of the App or from its interactions with operating systems, audio sessions, Bluetooth, or battery;

g) Personal injury or property damage caused by decisions made on the basis of AI Output without proper professional verification (e.g. failure to identify a mechanical, electrical, ATEX or chemical hazard; failure to size a safety distance per EN ISO 13857; failure to spot an unguarded movable guard, etc.);

h) Loss, alteration, corruption, deletion of data (photos, inspections, reports, configurations, API keys, conversations) — even if caused by App bugs, iOS updates, device malfunctions, phone replacement, factory resets, iCloud sync failures, accidental uninstallation;

i) Unavailability, interruptions, modifications, suspensions of the AI Providers selected by the User (Anthropic, OpenAI, Google) and of third-party services (Twilio, n8n, RAVENG portal);

j) Unforeseen costs: excessive API charges, account suspensions with AI Providers, data overconsumption, rate-limit hits, etc.;

k) Privacy violations of third parties committed by the User by acquiring images in places or of subjects for which the User had no valid title;

l) Violations of safety, CE conformity or technical regulations committed by the User on the basis of AI Output without proper validation;

m) Force majeure: strikes, natural disasters, acts of terrorism, wars, pandemics, governmental restrictions, prolonged unavailability of digital infrastructure or cloud services;

n) Decisions of Apple Inc. regarding publication, suspension or removal of the App from its App Store / TestFlight;

o) Decisions of Meta Platforms Inc. regarding availability of the Wearables DAT SDK, eligibility of Ray-Ban Meta devices for camera streaming, or future changes to hardware policies.

9.2 Monetary cap

Without prejudice to the above and subject to the unwaivable cases of wilful misconduct or gross negligence (art. 1229 Italian Civil Code) and of breach of mandatory privacy obligations, the aggregate liability of the Indemnified Parties towards the User, for any cause connected to the App, is in any case limited to the amount the User has paid for the use of the App in the twelve months preceding the harmful event. Since the App is free of charge, such cap is symbolically set at € 50.00 (fifty euros).

10. INDEMNIFICATION BY THE USER

10.1 Indemnification obligation

By using the App and accepting these Terms, the User expressly and irrevocably undertakes to indemnify, hold harmless and defend the Indemnified Parties — being RAVENG by CE4U S.r.l., Mr Carlo Tenca personally, the domain raveng.it and their respective directors, members, employees, collaborators, consultants, suppliers and assigns — from every claim, dispute, action, proceeding, judgment, sanction, damage, cost, charge or expense (including legal fees and expert/consulting costs) — by way of illustration and not limitation:

a) Brought by third-party subjects (User's clients, professional counterparties, supervisory authorities, employees, trade unions, judicial bodies) as a consequence of damages, errors, omissions or non-compliances arising from the User's use of the App, third parties' reliance on AI Output or generated reports, or the lack of or insufficient professional verification of the Output;

b) Arising from improper, incorrect, illegal, or out-of-scope use of the App by the User;

c) Arising from breach of safety, CE, technical-compliance, privacy, copyright or trademark regulations committed by the User using the App;

d) Arising from enquiries, investigations or actions of authorities (Italian Garante Privacy, UK ICO, US FTC, equivalent foreign supervisory authorities, Labour Inspectorate, INAIL, Public Prosecutor's Office, Court of Auditors) connected with the User's use of the App;

e) Arising from acquisition of images or recordings in violation of privacy rules, industrial secrets, national security or workplace regulations;

f) Connected with use of third-party AI Providers in breach of their acceptable-use policies.

10.2 Personal extension to Carlo Tenca

The User acknowledges and accepts that the indemnification under §10.1 expressly extends to the natural person of Mr Carlo Tenca, as member/director of CE4U S.r.l. and designer of the App, and to his family, heirs and assigns, irrevocably declaring to waive any claim against him personally save for cases of personal wilful misconduct under art. 1229 Italian Civil Code.

10.3 Joint defence

In case of action brought by third parties involving the Indemnified Parties, the latter shall be entitled to:

a) Freely choose their own counsel; b) Determine the defence strategy; c) Settle the controversy without the User's consent being required; d) Require the User to intervene in the proceedings pursuant to Italian Civil Procedure Code art. 269; e) Require from the User full reimbursement of legal and expert fees incurred.

10.4 Non-replacement

This indemnification is cumulative and not in substitution of the other limitations of liability provided by these Terms (§§ 7, 8, 9) and by applicable law.

11. Personal data processing

The processing of personal data is integrally governed by the Privacy Policy accessible in Settings → About → Legal Documents within the App.

The User acknowledges and accepts that by enabling cloud AI features the data (photos, prompts, conversations) will be transmitted to the AI Provider chosen by the User, in accordance with the Privacy Policy.

12. Trademarks and distinctive signs

The marks "Iridai" and "RAVENG" and the shutter/iris logo are the exclusive property of RAVENG by CE4U S.r.l.

Third-party trademarks cited (Ray-Ban Meta, Apple, iPhone, Anthropic, Claude, OpenAI, ChatGPT, Google, Gemini, Twilio, n8n) are property of their respective owners and are used solely for descriptive purposes.

13. Amendments to the Terms

RAVENG reserves the right to amend these Terms at any time. Changes will be communicated in Settings → About → Legal Documents within the App, with indication of the effective date.

For substantial changes adversely affecting the User's rights, renewed explicit acceptance will be required. Continued use after non-substantial changes constitutes tacit acceptance.

14. Suspension and termination

The User may cease use at any time by uninstalling the App.

RAVENG may suspend or terminate the provision of the service:

a) For breach of these Terms by the User; b) For technical, security or force-majeure reasons; c) For project discontinuation, with at least 30 days' notice where possible, save in urgent cases.

In case of termination, the User may export their local data (PDF reports, inspections) up to the moment of uninstallation. The clauses on exclusion and limitation of liability and on indemnification (§§ 7, 8, 9, 10) survive termination of the relationship.

15. Force majeure

Neither party shall be liable for failure to perform these Terms caused by events beyond reasonable control: strikes, natural disasters, acts of terrorism, wars, pandemics, governmental restrictions, prolonged unavailability of digital infrastructure or third-party services (cloud AI providers, Apple, Meta).

16. Governing law and jurisdiction

These Terms are governed by Italian law.

For any dispute arising from the interpretation, performance or termination of these Terms, the Court of Verona shall have exclusive jurisdiction — save for the unwaivable consumer-protection venues set out in art. 66-bis of Italian Legislative Decree 206/2005 (residence or elected domicile of the consumer-User), where applicable.

For users outside Italy who do not qualify as consumers under Italian law, the parties acknowledge that the choice of Italian law and Verona venue may not be fully enforceable, and undertake to attempt amicable resolution before bringing any action.

17. Final provisions

a) If any clause of these Terms is declared null, invalid or ineffective by a competent court, the remaining clauses shall remain fully valid and effective (severability); b) These Terms constitute the entire agreement between the parties and supersede prior oral or written agreements on the same subject matter; c) Any tolerance by RAVENG of breaches of the Terms shall not constitute waiver of its rights; d) Official communications between the parties shall be sent to the email address set out in §1 or to the PEC certified-email address RAVENG may indicate later.
