Terms of Use and Purchase

Who we are

DFW AI Services LLC, doing business as Cortova, publishes CortovaVoltPrep, an independent electrician licensing exam-preparation program.

Cortova is an independent exam-preparation publisher. Cortova is not the licensing authority, not the exam vendor, and not the official publisher of the National Electrical Code. Cortova is not affiliated with, endorsed by, or approved by the Texas Department of Licensing and Regulation (TDLR), PSI, or the National Fire Protection Association (NFPA). Passing a Cortova practice session is not a license, a credential, or a guarantee of an exam result.

Your license to use the course

A purchase grants you a personal, limited, non-exclusive, non-transferable, revocable license to use CortovaVoltPrep for your own exam preparation during your access period.

Copying, recording, screen-capturing, sharing, reselling, scraping, reverse-engineering, or sharing an account is prohibited. The question bank, explanations, calculations, drills, videos, narration, and job aids are copyrighted and proprietary.

The Cortova name and mark are trademark-pending. Violations may result in termination of access without refund.

Purchase paths and access periods

Full Pass includes both the NEC Knowledge lane and the Calculations lane for 90 days from payment.

Technical Knowledge Only (Rescue) includes the NEC Knowledge lane for 60 days from payment.

Calculations Only (Rescue) includes the Calculations lane for 60 days from payment.

A Rescue purchase may be upgraded to Full Pass by paying the difference between the two prices; the upgrade unlocks both lanes and applies the Full Pass access period from the original purchase date or extends to 90 days from the upgrade, whichever is later.

Every price is flat and permanent. There is no introductory tier, no seat count and no deadline: the price shown at checkout is the price you pay, and a price change never applies to a checkout already started.

You may request one free 30-day courtesy extension, once, for the life of your account — for example if you failed a portion and are retaking it, or if you simply need more time. It is granted on request from your account page, it extends your existing access rather than starting a new enrollment, and the reason you give is recorded with it.

After the free courtesy extension is used, further access is sold in 30-day extensions at the price shown on your account page, which differs for the Full Pass and for a single-lane package. An extension always extends your existing access and never creates a second enrollment.

Referral codes and rewards

Every paid Full Pass enrollment receives two single-use referral codes. Each code expires 14 days after it is issued and may be given to one person.

A referral code is not a discount. The person you refer pays the same published price as everybody else; the code identifies you so that your reward can be paid.

For each successful referred purchase you receive seven extra days of access, capped at fourteen extra days in total, applied after the referred payment clears. Each student may redeem one referral code, once, and may not redeem their own.

If a referred purchase is refunded or charged back, the related reward days are reversed or flagged, and unused codes tied to a refunded or charged-back purchase are disabled.

Refund policy

Refunds are permitted within 7 days of purchase only if all of the following conditions are met:

• Less than 10% of the course has been completed.
• No major assessments have been taken.
• No referral benefits have been used.
• No terms have been violated.

All sales are final, except at Cortova's discretion.

Chargeback procedure

If a chargeback is initiated, we will:

• Pause access immediately.
• Disable any unused referral codes.
• Pause or flag any bonus days.
• Treat the course content as copyrighted and proprietary and respond to the dispute accordingly.

Student notes

Notes are for your own summaries, paraphrases, and calculation reminders. Copying or reproducing course content into notes is not permitted. Notes are checked for large blocks of copied course text; confirmed copying is logged, and after three confirmed incidents the notes feature is disabled for that account while course access continues.

Records and administration

Checkout consents, purchases, refunds, denials, access changes, referral events, note actions, and support tickets are recorded in an append-only audit log with timestamps and the policy version in force. Administrators review eligibility and approve or deny requests with a recorded reason.

Changes

These terms are version 2026-09-03.3. Cortova may update them; the version you agreed to at checkout is recorded with your purchase.
