• Technical steps: (1) choose a plan on the pricing page → (2) create an account or sign in → (3) enter billing details on the secure Stripe page → (4) confirm payment → (5) receive a confirmation email. The contract is concluded at the moment of payment confirmation.

3. Nature of the service

The ZEPHREN calculation program is a software tool for calculating building energy performance, compliant with Mc 001-2022, Ord. MDLPA 16/2023, EPBD 2024/1275, and Law 238/2024. Generated outputs (CPE, audit report, renovation passport) are professional aids — final responsibility for input data accuracy and result interpretation lies with the certified energy auditor who signs the document.

AI functions and AI literacy (EU AI Act 2024/1689 Art. 4): Zephren integrates artificial intelligence functions (invoice/CPE OCR, envelope suggestions, narrative generation, chat assistant) provided through third-party language models. These functions are ASSISTIVE (minimal risk per Art. 6 AI Act) and do NOT substitute the auditor's professional judgment. The user is obliged to manually verify all AI outputs before including them in official documents (CPE, audit). Details in the "AI Use Policy" (available on request via legal@zephren.ro).

4. Accounts and subscriptions

The Service is offered in subscription tiers (Pricing v9.0, founder decision D18, effective 24 September 2026 — supersedes v8.0 of 22 May 2026), billed monthly OR annually, at the user's choice:

• ZEPHREN Free — 0 RON. A new account receives, upon entering the MDLPA attestation number, a full-access trial on its own projects: all eight steps, with the certificate, Annex 1 and Annex 2 and the calculation brief in official form, unwatermarked. The trial lasts thirty days of full access or three official certificates issued, whichever comes first: at most three official certificates can be issued during the trial, and regenerating them does not count. No card is requested and there is no payment obligation; when the trial ends nothing is charged and the account stays free, with: unlimited data entry in Steps 1-4, the five M1-M5 examples in full (Steps 5-8 only on the examples) and AI Pack with no monthly limit. The trial is granted once per attestation number; the device identifier retained when it starts, and its retention periods, are described in the Privacy Policy (§2 and §5).
• ZEPHREN CPE — 349 RON/month or 2,990 RON/year: Steps 1-6 official CPE + MDLPA Annex 1+2 + 40mm stamp + unlimited AI Pack + unlimited Cloud sync.
• ZEPHREN CPE + Audit — 599 RON/month or 4,990 RON/year: full CPE + Step 7 Mc 001-2022 audit + nZEB conformity report (Art. 6 para. 1 letter c) + all building types + hourly EPW climate.
• ZEPHREN Advanced Analysis — 899 RON/month or 7,490 RON/year: full CPE + Audit, plus Step 8 (54 advanced modules) + BIM + Pasivhaus + MonteCarlo.
• ZEPHREN CPE — per certificate — 149 RON, one-time payment, no subscription: a single CPE certificate, for users who issue occasionally.

"Founding members" offer: the first 50 subscribers who activate an ANNUAL subscription with the promotional code FONDATOR50 receive a 20% discount for the whole life of the subscription ("for life" — as long as the subscription stays active, without interruption). The offer applies exclusively to annual subscriptions, is limited to the first 50 users who claim it and cannot be combined with other discounts.

VAT: ZEPHREN S.R.L. is not VAT-registered under the Romanian small business exemption (Tax Code Art. 310 — turnover below395,000 RON/year ≈ 79,000 EUR, threshold raised from 300,000 RON effective 1 September 2025 by Government Ordinance 22/2025). Listed prices are final, with no VAT added. Any change upon exceeding the 395,000 RON legal threshold will be announced in advance, by email. Only operations with the place of supply in Romania are counted toward the threshold.

Full details and updated pricing are on the pricing page (www.zephren.ro/preturi). Subscriptions auto-renew at the end of each billing cycle (monthly or annual, as chosen). Price changes are announced in advance, by email, before applying.

5. Cancellation and refunds

Cancellation of the subscription is possible anytime, without penalties, from the Stripe Customer Portal admin panel (link in Settings → Plan → "Manage subscription"). Cancellation takes effect at the end of the current paid cycle — benefits remain active until the end of the paid period (the month or the year, according to the chosen cycle).

No proration on cancellation: cancellation stops the renewal, and the part of the period already paid is not refunded automatically — access stays active until the end of the paid period. This rule concerns ordinary cancellation and does not restrict the withdrawal right described below.

Consumer right of withdrawal: a consumer user keeps the 14-day right of withdrawal provided by Romanian GEO no. 34/2014 on consumer rights. ZEPHREN does not request and does not record, at purchase, a consent to the immediate start of performance or an acknowledgement of losing this right; therefore the right of withdrawal is not extinguished merely because use of the Service has started. A withdrawal request received after the Service has already been used is not rejected automatically: it is reviewed individually by the ZEPHREN team, and the decision is communicated by email.

B2B exception: for legal entity clients (audit firms), consumer withdrawal rights do not apply. Cancellations follow standard commercial terms.

Refund in case of technical error: if the Service was unavailable over 24h continuously (downtime confirmed by ZEPHREN in writing, via email and/or via in-app notification) and the user could not issue planned CPEs, ZEPHREN may grant a credit or pro-rata subscription extension (request at billing@zephren.ro).

Plan transitions: upgrade between plans takes effect immediately (Stripe Customer Portal calculates pro-rata for the current month). Downgrade takes effect at the end of the current cycle (NOT mid-cycle, to avoid blocking access to features already used).

6. Service availability (SLA)

ZEPHREN commits to a target availability of ≥99.5% calculated monthly, excluding planned maintenance windows announced at least 48 hours in advance.

Periods of unavailability are officially confirmed by ZEPHREN through its official channels: written confirmation via email and/or in-app notification. Major incidents are communicated via email and in-app notification.

Downtime compensation: if monthly availability falls below 99% (over 7h 12min cumulative downtime), users with active subscription can request a pro-rata credit or subscription extension. Request at billing@zephren.rowithin 30 days of the incident.

6.bis Assistance

Assistance with the Service is provided through the in-app AI assistant (the "Help" button) and the help centre (zephren.ro/help). A problem the assistant cannot solve is recorded automatically as a ticket, together with the conversation and its context (the page and step you were on), and the ticket number is shown to you in the application. The data processed for tickets is described in the Privacy Policy.

Legal notices, the right of withdrawal, billing and personal-data requests continue to go to the addresses given in these Terms and in the Privacy Policy.

7. Intellectual property

Source code, design, logo, and calculation algorithms are the property of ZEPHREN S.R.L. The user receives a non-exclusive, non-transferable license for professional use. Data entered by the user remains their property.

8. Limitations of liability

The Service is provided "as is". ZEPHREN S.R.L. is not liable for: (a) errors in data entered by the user, (b) incorrect interpretation of results, (c) punctual service interruptions caused by external providers (Vercel, Supabase, Stripe, AI model vendor).

For legal entity clients (B2B), maximum total liability is limited to the amount paid in the last 12 months of subscription. For consumers (natural persons, including PFA sole traders), NO limitations apply that would contravene Romanian Law 193/2000 on unfair contractual terms or art. 1.350-1.353 of the Civil Code on contractual liability. These limitations do not apply in case of fraud or gross negligence by ZEPHREN (art. 1.355 Civil Code).

9. Acceptable use

The user commits not to: (a) use the Service for illegal purposes, (b) attempt to compromise security, (c) use automated scripts for massive API calls, (d) enter client data without their GDPR consent.

10. Termination

ZEPHREN S.R.L. may suspend accounts in case of Terms violation. Upon termination, the user's personal data will be anonymized or deleted per the Privacy Policy.

11. Applicable law and dispute resolution

This contract is governed by Romanian law. Disputes are resolved through the following channels, in order:

• (a) Amicably — request to legal@zephren.ro with a 30-day response deadline.
• (b) Consumers (natural persons, including PFA sole traders): per Art. 113 para. (1) letter e) of the Romanian Code of Civil Procedure, the competent court is that of the consumer's domicile.
