SummerFlow · Last updated: 26 October 2026
SummerFlow is a software service operated by Permanent Summer, Lda., a company registered in Portugal, NIPC 516416804, registered office Casas da Alcaria, Lote 81, 8950-413 Altura, Portugal ("SummerFlow", "we"). Contact: christopher@permanentsummer.co.
SummerFlow is a business tool for short-term rental hosts and property managers ("you", the "host"). You must be at least 18 and use the service for professional purposes. By creating an account, you accept these terms. If you act for a company, you confirm you can bind it.
SummerFlow lets you manage properties, reservations, direct booking requests, cleaning, notifications and finances, and offers a public booking page for your guests. Figures shown (revenue, occupancy, expenses, amounts owed) are calculated from the data you enter. They are for management purposes only and are not accounting, tax or legal advice. Check important figures yourself before relying on them, for example before paying staff or filing taxes.
SummerFlow is currently offered free of charge during the launch period. We may introduce or change paid plans; we will give at least 30 days' notice before any change that affects what you pay or lose. Some features, such as removing the "Powered by SummerFlow" notice, may be reserved for paid plans.
You own the content you put into SummerFlow ("your data"). You give us the right to store, process and display it only to provide the service to you, as described in our Privacy Policy.
For your guests' personal data you are the data controller and SummerFlow is your processor. The data-processing terms in the Privacy Policy (section "Processor terms") form the data processing agreement between us under Article 28 GDPR. You are responsible for having a legal basis to collect guest data, for informing your guests, and for your own legal duties as a host.
You can export your data and delete your account at any time (Account → Delete my account). Deletion removes your data from our live systems; see the Privacy Policy for backups.
You alone are responsible for: the accuracy of prices, availability, descriptions and photos; having the licences and registrations required for your rentals (for example the Alojamento Local registration and any guest-registration, tourist-tax, tax and insurance obligations); consumer-protection and booking terms with your guests; and your content respecting other people's rights. If you import data from platforms such as Airbnb or Booking.com, you must respect their terms.
A booking request is an arrangement between you and your guest. SummerFlow is not a party to it, does not process payments, does not hold deposits and does not guarantee bookings, availability or guest behaviour. Payment details shown to guests are the ones you provide. A "Powered by SummerFlow" notice is shown on public booking pages and must not be removed or hidden unless your plan allows it.
When you confirm, decline or reply to a request, SummerFlow sends emails to your guests on your behalf, from a SummerFlow address with your email set as the reply address. Only use this for messages related to real bookings and requests. No spam, no marketing to people who did not ask for it.
Do not: access or try to access other users' data; probe, overload or attack the service; reverse-engineer it; send spam; upload unlawful or infringing content; or use the service for anything unlawful. We may suspend or close accounts that do, with notice where possible (immediately if the risk is serious).
SummerFlow, its software, design and name belong to us. You get a limited, revocable, non-transferable right to use the service while your account is active.
We work to keep SummerFlow reliable and secure, but we provide it "as is" and cannot guarantee uninterrupted service. We may update, change or remove features. We recommend you keep your own copy of important data (use the export function regularly).
To the extent the law allows: we are not liable for indirect or consequential loss, lost profits, lost bookings or loss of data caused by events outside our reasonable control or by your own inputs; and our total liability to you for any claim related to the service is limited to the greater of the amount you paid us in the 12 months before the claim and €100. Nothing excludes or limits liability that cannot be excluded or limited by law (for example for intent or gross negligence).
You will compensate us for third-party claims caused by your breach of these terms or by your content.
You can stop using SummerFlow and delete your account at any time. We may end or suspend the service to you for serious breach, or for any reason with 30 days' notice. Sections that by their nature should survive (liability, intellectual property, governing law) continue after the end.
We may update these terms. For material changes we will notify you by email or in the app at least 30 days before they apply. If you keep using SummerFlow after that, you accept them; if not, you can delete your account.
Portuguese law applies. The courts of Faro have jurisdiction, without prejudice to mandatory rules. If any part of these terms is invalid, the rest continues to apply. These terms are written in English; translations are for convenience.
