Previaly Terms of Use

Translation. This English version is provided for convenience. The Portuguese version is the binding one: if the two differ, the Portuguese text prevails.

These Terms govern the use of the Previaly platform, available at previaly.com. By creating an account, accepting these Terms or using the dashboard, you agree to them and to the Privacy Policy.

If you don't agree, don't use the service.

1. Who we are and acceptance

Previaly is the Previaly platform, available at previaly.com ("we", "us").

These Terms apply to whoever registers an optical store and uses the dashboard (you, the store owner). The customer who opens the storefront on their phone doesn't create an account with us: they use the link you share. How that customer's camera is handled is described in the Privacy Policy.

Previaly is a service for optical stores. You declare that you are at least 18 years old and authorized to represent the store you register.

2. The service

Previaly offers:

  • Dashboard: setup of the store, frames, photos, categories, look and contact details.
  • Storefront: a public page at previaly.com/your-store, with the catalog you publish.
  • Virtual try-on: visitors who allow the camera see the frame on their own face, in their phone's browser, in real time, with no app to install.
  • AI Studio: dashboard tools to clean up frame photos and create catalog images. These use credits. The try-on itself doesn't use credits.

The try-on doesn't replace an in-person fitting, measurements checked in the store or an eyeglass prescription. It helps the customer see how a frame's style looks on their face. The sale, the payment for the frame and customer service are between you and your customer, usually through the WhatsApp number you registered.

We don't promise clinical use, medical reports or sales without human review.

3. Sign-up and account

To use the dashboard you provide an email address and a password. Then you register the store's name and the storefront address (the last part of previaly.com/your-store).

You are responsible for:

  • keeping your password secret;
  • everything done in the account, including by people you invite;
  • keeping your email and store details true and up to date.

Each store has one main account holder. Other people only get access if you add them.

If someone uses your password, let us know at contatoprevialy@gmail.com or on our support WhatsApp (+55 21 95948-3883) so we can end the session.

Don't share one account among different stores to get around your plan's store limit.

4. Plans, credits and billing

Advertised plans

The homepage lists:

  • Basic — Price: R$ 97. AI credits per month: 80
  • Pro — Price: R$ 147. AI credits per month: 180
  • Ultra — Price: R$ 497. AI credits per month: 600

Prices are in Brazilian reais (R$). Credits are only for the AI image tools. Trying on frames doesn't use credits.

Today stores start on the Free plan; if we create a time-limited trial, its rules will be added here and we'll let you know by email. New stores join the Free plan, with a monthly credit allowance. Paid plans are arranged through a WhatsApp conversation, and we can change your plan for you.

Once payment is active

Monthly billing will be processed by a payment partner. We don't store card numbers or security codes. That data, if any, stays with the partner.

The fee is charged monthly, in advance, in Brazilian reais, unless otherwise agreed in writing.

Credits

  • Your allowance renews every month. Unused credits don't roll over to the next month.
  • Until there is a paid subscription cycle, the period is the calendar month.
  • If image generation fails because of a problem on our side, the credit for that attempt is refunded. You don't pay for our defects.
  • If the photo is generated and you don't like the result, that isn't an automatic refund. You can generate it again, using new credits, or contact support.
  • When your allowance runs out, generation stops; the storefront and the try-on for photos already published keep working. To keep generating, contact us on our support WhatsApp.

Price changes

We may change prices and allowances. We'll give at least 30 days' notice by email or in the dashboard. If you don't agree, cancel before the change takes effect. Any period already paid runs until its end.

Late payment

An overdue invoice may lead to the dashboard being suspended and, if it continues, to the account being closed. The storefront may be paused. Published content may go offline until payment is settled.

5. Store owner content

You upload and publish: frame photos, name, brand, model number, price, measurements, logo, cover image, text, WhatsApp, address, social profiles and anything else the dashboard asks for.

You declare that:

  • you have the right to use those photos, brands and texts;
  • the content doesn't infringe anyone's rights or the law;
  • the product information is what you want to show your customers.

You grant us a limited, non-exclusive license to store, display on the storefront, process (including cleaning up frame photos with AI) and make the technical copies needed to provide the service. We don't sell your catalog to other stores.

Photos of people that you upload are your responsibility: get permission from whoever appears in them.

Shared 2D catalog

The try-on's 2D model is generated and processed by Previaly from the frame photo. When a frame is live and has a model number, the 2D model, calibration, model number, brand, name and measurements may enter a catalog that other Previaly stores use to get the try-on for the same frame without generating it again. So they can confirm it's the same frame, the main photo may be shown to them inside the dashboard, only for that choice.

That catalog doesn't include your price, your storefront or your customers, and other stores don't use your photos on their storefronts. Models that entered the catalog remain available even if the frame or the account is closed. If you don't want a frame to enter it, leave the model number blank or contact support.

6. Acceptable use

You agree not to:

  • use the service for fraud, spam or illegal content;
  • try to get around credit payments, the store limit or security locks;
  • attack or overload the platform;
  • send the AI images that aren't of the store's products in order to exploit the paid tools;
  • register minors as store owners;
  • impersonate another store.

The try-on and the storefront are for your customers to choose frames. Don't use the service to monitor people, recognize identities or build a database of faces.

7. Artificial intelligence and review

The AI studio recreates and cuts out the frame photo. The result may have flaws (background, temples, reflections, color).

You review it before publishing. What goes on the storefront and the try-on is what you approved. We're not responsible if a customer is disappointed by a photo you published without checking.

The AI never receives photos of your customers' faces. Only the product photo you uploaded in the dashboard.

8. Availability and support

We provide the service on a best-effort basis. We don't promise a minimum uptime, unless under a separate signed contract.

The site may be offline for maintenance, provider failures or events beyond our control. We'll do what's reasonable to restore it.

Support: WhatsApp +55 21 95948-3883, or contatoprevialy@gmail.com. Business hours in Rio de Janeiro, Brazil, unless the dashboard says otherwise.

The try-on depends on the visitor's camera, browser and device. An old device, a blocked camera or an unstable connection may prevent the try-on. That isn't a breach on our part as long as the storefront itself opens.

9. Platform intellectual property

Previaly — the brand, code, dashboard design, our texts and page templates — belongs to us or to whoever licensed it to us. These Terms don't transfer the platform to you.

You remain the owner of the content you uploaded, as set out in section 5.

Don't copy the dashboard, extract the try-on engine or resell access as your own product without written permission.

10. Suspension and termination

We may suspend or terminate access, with notice proportional to the seriousness, if you:

  • breach these Terms;
  • don't pay for your plan once billing is active;
  • abuse the AI or the security measures;
  • create legal risk for us or for third parties.

You may close your account at any time by asking at contatoprevialy@gmail.com or on our support WhatsApp. Requests go through these contact channels.

When you leave:

  • the storefront goes offline;
  • we may delete or anonymize the store's data after the period set out in the Privacy Policy;
  • if you ask, we'll deliver a reasonable package of what's yours (account details, frame list, files that still exist), in a common format, within 15 days, unless complexity justifies a longer period communicated in writing;
  • unused credits aren't refunded in cash, unless required by law or caused by a proven failure on our side.

If the storefront is paused, its address stops serving the catalog until it's turned back on.

11. Limitation of liability

To the extent permitted by Brazilian law:

  • the service is provided as is, on a best-effort basis;
  • we're not liable for lost profits, the loss of a specific sale at the counter, or for what your customer decides after using the try-on;
  • our total liability for matters related to these Terms, in any 12-month period, is limited to the amount you paid us in that period (or, if you're still on the free plan, the equivalent of one month of the advertised Basic plan).

Nothing in this section excludes:

  • damage caused by our willful misconduct or gross negligence;
  • non-waivable rights under the Brazilian Consumer Protection Code (Law 8,078/1990), when the relationship is a consumer one — which, for this service, is generally not the case for the store, but may be assessed case by case;
  • liability that the law doesn't allow to be limited.

The storefront's end customer doesn't pay Previaly. Issues with buying the frame, product warranty and lens fitting are the store's responsibility, not the platform's.

12. Changes to these Terms

We may update these Terms. The date at the top will change. Significant changes will be announced by email or a notice in the dashboard, with reasonable advance notice when the law requires it.

Using the service after the new version takes effect counts as acceptance, unless the law requires express consent. If you don't agree, close your account before then.

The current version is at https://previaly.com/termos (Portuguese) and https://previaly.com/en/terms (this translation).

13. Governing law and jurisdiction

Brazilian law applies, in particular the Brazilian Internet Civil Framework (Law 12,965/2014) and the Brazilian General Data Protection Law, LGPD (Law 13,709/2018).

The courts of Rio de Janeiro, Brazil, are chosen to settle any dispute, waiving any other, except for the consumer's place of residence when the law requires it.
