Terms of Use

Last updated: October 25, 2026

In short

Aveiro helps you build sites, grow an audience, and send email. Use it lawfully, pay for plans you choose, and keep your account secure. Paid plans renew automatically until you cancel, and payments are generally non-refundable. You own your content; we host it. Our liability is limited as described below.

Agreement

These Terms of Use ("Terms") govern your access to and use of Aveiro at aveiro.app and related services (the "Service"), operated by Aveiro ("we", "us", "our"). By creating an account or using the Service, you agree to these Terms and our Privacy Policy. If you do not agree, do not use the Service.

What Aveiro is

Aveiro is an online platform that lets you:

Build and publish websites (including on {slug}.aveiro.page and optional custom domains)
Edit content visually, manage media, and use AI-assisted editing tools
Collect email subscribers, organize segments, and send campaigns or automations
View privacy-friendly analytics for your sites
Collaborate in organizations with role-based access
Draft, approve and schedule social posts published to connected accounts
Subscribe to paid plans with usage credits for email, AI and social publishing

Features vary by plan. Some capabilities (such as custom domains, BYOK email providers, or higher limits) require a paid subscription.

Eligibility

You must be at least 18 years old (or the age of majority where you live) and able to enter a binding contract. During closed beta, signup may require a valid invite code or waitlist approval. We may change beta access rules at any time.

Your account

You are responsible for:

Providing accurate registration information
Keeping your password and account credentials secure
All activity under your account
Ensuring collaborators you invite comply with these Terms

Notify us promptly at support@aveiro.app if you suspect unauthorized access. You may delete your account at any time from Settings → Security. Deletion is subject to confirmation and may not immediately remove all backups or logs retained for legal or security purposes.

Subscriptions and billing

Paid plans are billed through Stripe. By subscribing, you authorize recurring charges at the price shown at checkout until you cancel.

Prices, features, and credit allowances are described on our pricing page and may change with notice for future billing periods
Taxes may apply depending on your location
Failed payments may suspend access until resolved

Automatic renewal

Paid subscriptions renew automatically at the end of each billing period (monthly or annually, as you chose) and the payment method on file is charged the then-current price, unless you cancel before the renewal date. If you start a paid trial, it converts to a paid subscription when the trial ends unless you cancel first. We email the organization owner a reminder before each renewal charge: 7 days before a monthly renewal and 30 days before an annual renewal. The reminder states the renewal date, the plan price, and how to cancel. Please keep your account email up to date — a reminder that doesn't reach you because of an outdated address, a full inbox, or spam filtering doesn't change the renewal.

Cancellation

You can cancel at any time from Billing in your organization's dashboard. Cancellation stops future renewals; you keep access to paid features until the end of the period you have already paid for, and are not charged again.

Refunds

Payments are non-refundable, except where this section or applicable law says otherwise. In particular:

Renewal charges — including automatic monthly and annual renewals — are not refunded once processed, whether or not you used the Service during the new period. Cancel before the renewal date to avoid the next charge.
Partial periods — we do not refund or credit unused time when you cancel or downgrade mid-period.
Credits and top-ups — purchased credits are not refundable and have no cash value.

We may, at our sole discretion, issue a refund or credit in exceptional cases, such as a duplicate charge or a billing error on our side. Doing so once does not oblige us to do so again. Contact support@aveiro.app about any charge you believe is wrong; please contact us before disputing a charge with your bank. Your statutory rights are not affected. If you are a consumer, the law where you live may give you rights that cannot be waived by contract — for example, a right to withdraw from a purchase within a set period, or to a remedy if the Service is faulty. Nothing in these Terms limits those rights.

Payments you schedule or authorize

You are responsible for every charge that you, members of your organization, or tools and integrations acting on your instructions schedule or authorize — including subscription renewals, plan changes, credit top-ups, and recurring or scheduled purchases. We process those payments as instructed and are not responsible for charges that result from a subscription or scheduled payment you did not cancel in time, or from a collaborator you gave billing access to. If you sell products, memberships, sponsorships or ads to your own customers through Aveiro, those sales are between you and your customers. You set and honor your own refund terms toward them; we are not the seller and are not responsible for refunds of those payments. Usage of email sends, AI features and social publishing consumes plan credits. Each pool has its own monthly allowance; top-up credits are shared and never expire. Social publishing is metered per network write: one post to one connected platform, and one more for its first comment. Platforms that charge us per post cost proportionally more — X notably so, and considerably more again for a post containing a link. Only writes that actually publish are charged: a platform that rejects a post, or refuses its first comment, costs you nothing. Publishing to X requires a paid plan. Additional top-ups or overage may be offered separately.

Acceptable use

You agree not to use Aveiro to:

Violate any law or third-party rights
Send spam, phishing, malware, or deceptive content
Harvest or scrape data without permission
Upload illegal, infringing, harassing, or harmful content
Attempt to bypass security, rate limits, or access controls
Resell or sublicense the Service without authorization
Use the Service to build a directly competing hosting platform

Email is especially sensitive. You must:

Only email people who have a lawful basis to hear from you
Include accurate sender information and working unsubscribe links
Honor unsubscribe requests promptly
Comply with CAN-SPAM, GDPR, ePrivacy, CASL, and other applicable email laws

We may suspend or terminate accounts that abuse the platform or harm deliverability for others.

Your content

You retain ownership of content you create — sites, copy, images, subscriber lists, and campaigns ("Your Content"). You grant us a limited license to host, store, reproduce, transmit, and display Your Content only as needed to operate the Service (for example, publishing your site, delivering your emails, or generating AI suggestions you request). You represent that you have the rights to Your Content and that it does not violate these Terms or applicable law.

AI features

AI tools generate suggestions based on your prompts and context. Output may be inaccurate or incomplete. You are responsible for reviewing AI output before publishing or sending. AI usage is subject to plan credits and fair-use limits. We may change models, providers, or availability without notice.

Analytics and visitor data

If you enable analytics on a published site, you are responsible for informing visitors as required by law (for example, through your own privacy notice). Aveiro's analytics are designed to be cookieless for visitors, but you remain the controller for visitor data collected on your site.

Email subscribers and marketing

When you collect emails through Aveiro forms:

You are the data controller for subscriber data
You must provide a clear privacy notice and lawful basis for collection
Optional marketing-consent checkboxes on forms record what the subscriber agreed to

We process subscriber data on your instructions to store lists, send campaigns, and handle unsubscribes.

Third-party services

The Service integrates with third parties (including Supabase, Stripe, Resend, Vercel, and OAuth providers). Your use of those services may be subject to their terms. Custom domains require you to configure DNS correctly at your registrar. If you connect a bring-your-own email provider, you are responsible for that provider's compliance and deliverability.

Referrals and affiliates

Referral and affiliate programs may offer rewards when referred users subscribe to paid plans. Program rules, eligibility, and payouts may change. Fraudulent referrals may be voided. Affiliate features may be unavailable during closed beta.

Intellectual property

Aveiro's software, design, trademarks, and documentation are owned by us or our licensors. These Terms do not grant you ownership of the Service itself — only a limited right to use it while your account is in good standing. You may not copy, modify, reverse engineer, or create derivative works of the Service except as allowed by law.

Availability and changes

We strive for reliable uptime but do not guarantee uninterrupted access. We may modify, suspend, or discontinue features with reasonable notice where practicable. We may update these Terms by posting a new version on this page. Continued use after changes take effect constitutes acceptance. If you disagree with an update, stop using the Service and cancel your subscription.

Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant that the Service will be error-free, that email will reach every inbox, or that AI output will be accurate.

Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, AVEIRO AND ITS SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, GOODWILL, OR BUSINESS OPPORTUNITY. OUR TOTAL LIABILITY FOR ANY CLAIM ARISING FROM THESE TERMS OR THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM OR (B) USD $100. Some jurisdictions do not allow certain limitations — in those cases, our liability is limited to the fullest extent permitted by law.

Indemnity

You agree to indemnify and hold us harmless from claims, damages, and expenses (including reasonable legal fees) arising from Your Content, your email campaigns, your sites, or your violation of these Terms or applicable law — except to the extent caused by our own negligence or willful misconduct.

Termination

You may stop using the Service at any time. We may suspend or terminate your access if you breach these Terms, fail to pay, or if continued service poses risk to us or others. Upon termination, your right to use the Service ends. Provisions that by nature should survive (including liability limits, indemnity, and intellectual property) will survive.

Governing law and disputes

These Terms are governed by the laws applicable where Aveiro is established, without regard to conflict-of-law rules. If you are a consumer in the EU/EEA or UK, you may also benefit from mandatory protections in your country of residence, and you may bring disputes in your local courts where required by law. Before formal proceedings, we encourage you to contact support@aveiro.app so we can try to resolve the issue informally.

General

Entire agreement — These Terms and the Privacy Policy are the entire agreement between you and Aveiro regarding the Service.
Severability — If any provision is unenforceable, the rest remains in effect.
No waiver — Failure to enforce a provision is not a waiver.
Assignment — You may not assign these Terms without our consent. We may assign them in connection with a merger or sale.
