Frequently asked questions.

A clear, front-facing photo in decent light — a phone selfie is fine. Avoid sunglasses, heavy shadows across the face, group shots, and very small or blurry images. For restorations, photograph or scan the old print flat, in even light, filling the frame.

Yes — that's the core design constraint. The model is instructed to preserve your face, features, skin tone and hair exactly, and to change only the lighting, backdrop, attire and photographic treatment. Try the free generation and judge for yourself before paying anything.

Typically 20–60 seconds. If a generation fails, you're never charged for it — credits are only deducted for successful results.

Full Revival repairs damage and recovers natural color — the most popular choice. Repair Only fixes scratches, creases and fading but keeps the original black-and-white or sepia character. Colorize focuses on bringing monochrome photos into color.

No. Outputs are AI renderings, not compliant ID photographs, and official documents require photos taken to strict specifications. Use Nuvika for LinkedIn, résumés, bios, speaker pages and social profiles.

No, and it never will be. You buy a credit pack once with a single card payment through Stripe. Nothing renews, and you'll never be charged again unless you choose to buy another pack.

By Stripe, on Stripe's secure checkout page. We never see or store your card details. Stripe accepts all major debit and credit cards.

Credits never expire. They live on your account and aren't transferable between accounts — though nothing stops you from generating portraits of family members from photos you have the right to use (with their consent).

Three things: ① Stripe confirms your payment and shows a receipt. ② We add the credits directly to the Nuvika account matching your checkout email — normally within minutes, always within 12 hours. ③ They appear on your account page; nothing to redeem or type. Just make sure you register with the same email you use at checkout.

Give it up to 12 hours, and double-check that your account email matches the email you used at Stripe checkout. Still nothing? Email support with your Stripe receipt — we fix delivery issues within one business day, usually much faster.

Unused packs: full refund within 14 days. Partially spent packs aren't refundable in the standard case (compute is consumed per generation), but genuine quality problems are reviewed individually. Full details in the refund policy.

They're processed transiently — sent to the AI model, transformed, returned to your browser. We don't keep a server-side gallery of your uploads or results, and we never sell or reuse your photos. Full detail in the privacy policy.

On our server, kept deliberately minimal: your name, email, a securely hashed password and your credit balance — nothing else. That means your credits follow you across devices and browsers; just log in. Details in the privacy policy.

Only with their consent (for living subjects) and only photos you have the right to use. Restoring old family photos is exactly what the restoration desk is for. Impersonation and deceptive use are forbidden — see acceptable use.

Standard downloads are high-definition (around 1024px); Premium and Deluxe packs unlock higher-resolution outputs suitable for print. Every image downloads as a clean JPG with no watermark (free-trial images carry a watermark).

Failed generations are never charged. If a completed one has artifacts, run it again — results vary between runs, and most oddities disappear on a second attempt. Persistent problems? Tell us; that's what section 3 of the refund policy is for.

They're careful, plausible interpretations — the model can't know the true color of a 1960s dress from a black-and-white print. Faces and composition are preserved; colors are an educated reconstruction. We're upfront about this in the AI disclaimer.
