Rilievo terms

Version 3, 11 October 2026. Terms of the offer, licence and software use; AI limitations, professional review and liability.

1 Provider and scope

Rilievo is provided by CE4U S.r.l., a single-member company operating the RAVENG brand, Via G. Rossini 29/2, 37012 Bussolengo (VR), Italy; tax/VAT number 04731920239; REA VR-444364. Support: info@raveng.it. Certified email: posta@pec.ce4u.it.

The app helps professionals and organisations inventory machines, collect photographs and documents, annotate evidence and prepare preliminary assessments and reports with their selected AI engine. Actual access depends on version, device, subscription and configured services. Public availability is confirmed by the official App Store link and Apple's displayed status.

2 Licence and Apple purchases

An app distributed by Apple is subject to the Apple standard EULA unless its App Store page specifies a custom licence. This information supplements the commercial and usage description without reducing mandatory rights or changing Apple's payment terms. Applicable conditions are available before purchase confirmation.

Use is permitted on authorised devices under Apple's rules. Unauthorised distribution, purchase verification circumvention and use of material without rights are prohibited, subject to activities permitted by mandatory law.

3 Subscription

A 14-day free introductory trial is shown only when Apple returns that offer and the account is eligible. Actual availability and conditions appear in Apple’s purchase sheet before confirmation. Both periods provide the same app functions during an active entitlement. New collection, editing and starting AI jobs require a verified subscription. Reading and exporting saved records remain available without renewal.

Apple's confirmation determines amount, currency, taxes, period, renewal date and conditions. Other storefronts may apply different prices or currencies. Listed prices describe the planned offer and do not establish product availability in every country. Apple handles payment under the account's conditions.

Switching between monthly and annual follows Apple's displayed rules and timing. Check your current plan before changing to avoid overlapping purchases. “Restore purchases” recovers available entitlements through the same Apple account; it does not restore the local survey archive.

4 Renewal, cancellation, refunds and withdrawal

Subscriptions renew automatically unless cancelled under Apple's conditions. Manage or cancel in iPhone Settings > your name > Subscriptions > Rilievo. Check confirmation and expiry date. Deleting the app or GitHub token does not stop Apple's renewal.

Cancellation and refund are separate actions. Request Apple purchase refunds through Apple's channels under applicable rules and statutory rights. Automatic acceptance is not guaranteed and mandatory remedies are not excluded. For consumers, withdrawal and digital content/service supply exceptions follow applicable law and any declarations required in the purchase process; installation alone should not be assumed to waive withdrawal rights.

See Apple subscription management and refund requests.

5 Separate services and costs

Rilievo's subscription pays for the software. It does not include a ChatGPT plan, API credits or usage with any provider, paid web research, unlimited cloud capacity, paid GitHub services, connectivity, backup storage, full technical standards, laboratory tests or machinery consultancy. Local AI requires a compatible device and model. Cloud requires accounts, authorisations and a correctly configured environment. Providers may impose limits, waiting times, terms, costs or changes independently of Rilievo.

The app promises no fixed analysis turnaround. A PR, bot response acknowledgement or sync indicator is not an imported and verified result. If cloud is unavailable, retain the data and complete the guide's checks.

AI via token uses your key and contract with the selected provider, separately from the Codex Cloud account. A ChatGPT plan does not imply API credits. Usage, searches and additional requests (including corrections or retries) may be billed by the provider. In-app counters are informational and do not replace the provider’s statement. Image, reasoning and search capabilities vary by provider, model and account; text-only models do not analyse photos. A connection test does not establish a complete, correct machine assessment.

6 Technical limitations and human review

Rilievo RAVENG, provided by CE4U S.r.l. and developed by Carlo Tenca, is a support tool. AI may produce errors, omissions and fabricated information (‘hallucinations’), even when plausible. Every app-generated analysis, assessment and report is an UNVALIDATED DRAFT: before it is used, delivered or relied on for decisions, it must be checked, corrected and approved by a competent, experienced professional familiar with the machinery and applicable rules. The software does not certify conformity or safety and does not replace inspections, measurements or professional judgement. CE4U S.r.l. and Carlo Tenca do not automatically approve or sign the output. Liability and rights that cannot lawfully be excluded or limited remain unaffected.

Review is required for every engine, local, Codex Cloud and API via token, and all output, including OCR and plate readings, classifications, photographic coverage, risks, priorities, regulatory references, calculations, recommendations, translations, chat responses and reports labelled “final”. A title, completed job status, colour, score, absence of alerts, inspector name or PDF, Word, ZIP, JSON or Markdown export does not confer professional validation. A source or citation may be invented, outdated, inapplicable or related to another machine.

Before any use, customer delivery, signature, sworn appraisal or decision, the appointed professional must compare output with the actual machine and original evidence, verify data and calculations, consult applicable sources and standards, complete missing inspections, tests and measurements, correct errors and omissions, and document their own approval and responsibility. If a necessary check is missing, the result remains an UNVALIDATED DRAFT and must not be used or delivered as a final professional document. Reading or exporting alone does not replace these checks.

Purchase includes the software, not review, consultancy, certification, approval, sworn appraisal or signature by CE4U S.r.l. or Carlo Tenca. Such services require a separate professional assignment expressly accepted by the relevant person. The name of Carlo Tenca, RAVENG, CE4U or another professional in an interface, brand or document does not establish that person’s participation or approval.

Capture must follow the site’s safe working procedure. Do not remove guards or put body parts into hazardous areas to improve a photograph. The software does not control or stop machinery and must not be used as a safety device.

PDF typesetting and LaTeX source export retain UNVALIDATED DRAFT status. A logo, RAVENG style, entered name, signature block or revision number does not establish approval or signature by CE4U S.r.l. or Carlo Tenca. Do not present sections omitted because data is missing as completed checks with a positive outcome.

7 Data, cloud and confidentiality

Users retain rights in material they own and must have authority to capture, analyse and share others' material. Before cloud use, check customer permissions, lawful bases, notices, agreements and transfers. Submissions to GitHub/OpenAI and the selected API provider, including any routed providers, are not automatically anonymised. Technical activation in the app does not remove users' obligations or CE4U's obligations for processing under its control.

Use dedicated private repositories and restricted credentials. Retain and delete data under the assignment policy. Local deletion does not erase histories, chats, cloud copies or exports. See the app privacy notice.

8 Archive, backups and support

Export and verify copies before changing phones, reinstalling, deleting or significant updates. Survey restoration is not guaranteed by restoring a purchase or maintaining a cloud repository alone. A ZIP retains available files and requires content checks; it does not promise automatic reimport into the app.

Email info@raveng.it for software support with version, device, steps and the message, excluding tokens or confidential material. Software assistance and professional machinery consultancy are different activities; technical assignments require a specific agreement. No response time or service level is promised without express agreement.

9 Service conformity and liability

9.1 Own responsibilities

CE4U S.r.l. is responsible for its contractual and statutory obligations. Carlo Tenca remains subject to the liability imposed by law for his own conduct. His name in the app does not imply a professional engagement, review, approval or signature of individual outputs. Their draft status and the user’s duty to review them do not remove the provider’s or developer’s own responsibilities.

9.2 Mandatory rights

Nothing in these terms excludes or limits liability for intentional misconduct or gross negligence, breach of obligations arising from public policy rules, death or personal injury where protected by law, or any other liability that cannot lawfully be excluded or limited. Mandatory guarantees and remedies for digital content and services, consumer rights, applicable data protection obligations and all other non-waivable rights remain unaffected. These terms introduce no monetary liability cap.

9.3 Use and causation

The user is responsible for their own conduct under applicable law, including submitting content without authority, falsifying data, presenting unreviewed drafts as approved documents or attributing unauthorised approvals or signatures to CE4U S.r.l. or Carlo Tenca. Any contribution of such conduct to damage is assessed under the ordinary rules of legal responsibility, causation and evidence, taking account of the responsibilities of other parties involved. The user’s liability is not presumed merely because they used the app.

9.4 Limited indemnity for business users

This clause applies exclusively to users acting in the course of their business or profession; it does not apply to consumers. A business user shall indemnify CE4U S.r.l. and Carlo Tenca for amounts payable to third parties and reasonable, documented defence costs, only to the extent directly attributable to the user’s unlawful or improper conduct for which the user is legally responsible and its causal connection with the claim, both established under applicable rules of law. The indemnity excludes the share of any loss attributable to CE4U S.r.l., Carlo Tenca or persons for whom they are legally responsible, and does not transfer their obligations concerning the software, third-party rights or conformity of the services to the user. The beneficiary must promptly notify the user of an indemnity claim and provide the evidence supporting it. They may not impose settlements or admissions of liability made without the user’s prior written approval. Decisions of the competent authority and the ordinary rules on the burden of proof continue to apply. This clause governs only the parties’ internal relationship and does not restrict third-party rights or the powers of public authorities.

9.5 Effect

An unenforceable provision does not affect other valid provisions; the relevant mandatory rules apply. Acceptance of the terms or warning is neither a waiver of the user’s rights nor confirmation that every clause is enforceable.

10 Updates and governing law

Updates may change functions, requirements and compatibility. Future terms will show a version and date; pricing or renewal changes follow Apple's process and information. Changes do not reduce acquired rights or mandatory protection.

Italian law applies, subject to mandatory consumer law in the consumer's habitual residence. Consumers retain the jurisdiction provided by law; no different exclusive court is imposed. Contact the provider above for information or complaints.

Candidate 1.1.0 usage addition: review and CE framework

Completing the framework and recording a review in the app are the professional’s documentary steps. They do not replace examination of the machine, determination of applicable legislation, external professional approval, a signature or conformity-assessment procedures. A confirmed framework can become incomplete or require reassessment when evidence or facts change. Every unverified point and non-conformity must remain accurately represented.

A new AI result does not automatically approve a previous review. Before use or delivery, the professional checks currency, evidence version, sources, measures and every page of the files actually produced. A “reviewed” state records the operator’s declaration and does not attribute verification, approval, signature, professional engagement or responsibility for a particular assessment to CE4U S.r.l. or Carlo Tenca. All mandatory obligations and rights described in these terms remain unaffected.
