Terms of Service

The terms on which alpflo provides a property brief. By ordering a brief you agree to these terms. They state plainly what a brief is, and — just as plainly — what it is not.

alpflo (the "Service") provides Swiss property due-diligence briefs. The Service is operated by:

alpflo is the merchant of record for every brief you order: you contract directly with the Provider, not with a reseller.

A property brief is a one-time digital report. From a Swiss address you supply, alpflo resolves the parcel and assembles facts drawn from public Swiss registers and open geodata — building facts, zoning, ÖREB restrictions, and modelled context such as transit quality and solar potential — with provenance stated for every source.

Every data field carries exactly one of four honesty states: On record (confirmed in a primary register), None recorded (the register was queried and held nothing for this parcel), Modelled (derived from a calculation, API, or model — real, but not register-direct), or Could not resolve (an edge case alpflo could not complete). These states are the product. They are stated so you can judge each fact for yourself.

Some source registers close intermittently — the federal dwelling register, for instance, cannot be queried on Sundays or outside its operating hours. Where that makes a fact unavailable, it is reported as Could not resolve with the reason, never as None recorded: being unable to retrieve a fact is not evidence that none exists. Where this affects the per-apartment facts of a multi-dwelling building, you are told before purchase and you decide whether to have the brief made without them or to return later. Every other part of the brief is unaffected.

alpflo reports what the public record states. Swiss registers — including the Federal Register of Buildings and Dwellings (GWR) — can contain entries that are incomplete, out of date, or that deviate from physical reality. A value marked "On record" means the register holds it, not that it is correct. You must not treat any field as ground truth. For any binding decision, verify at the authoritative source.

A brief is an information product. It is not legal advice, not a property valuation or price estimate, and not an adjudication of what may be built on a parcel. Nothing in a brief creates an attorney–client, surveyor, appraiser, or advisory relationship. Zoning and ÖREB content describes the public record; only the competent authority can decide what a given project may do. Use a brief to orient yourself, then confirm with the relevant register, authority, or a qualified professional before you act.

By design, a brief permanently excludes the following. Their absence is a deliberate scope choice, not an oversight:

  • Natural-hazard exposure — flood, landslide, rockfall, and avalanche risk are not assessed. Consult the official federal and cantonal natural-hazard maps for these.
  • Property valuation — no price, market value, rent, or yield estimate is provided.
  • Heritage / ISOS status — protected-site and inventory classifications are not assessed.

A brief covers the themes alpflo states it checks for the parcel in question. Coverage varies by canton and by what each register publishes.

The price of a brief is shown before you order and is payable in Swiss francs (CHF). Payment is processed by Stripe; see the privacy notice for how your payment data is handled. A brief is delivered electronically, on screen and as a downloadable PDF, immediately after it is generated. A purchased brief stays directly retrievable through its confirmation link for 30 days; after that window, re-running the same property is a new order at the normal price.

A brief is a digital good delivered electronically, generated on demand when you submit the address, and made available to you immediately once payment completes. By completing your order you expressly request immediate delivery and acknowledge that you thereby waive your statutory right of withdrawal under Swiss law (OR Art. 40a–40f). The brief is non-refundable once delivered, except where generation fails entirely, in which case you are entitled to a full refund. The refund policy at Refund forms part of these terms.

You may use a brief for your own due diligence on a property you have a legitimate interest in. You must not resell, redistribute, scrape, or bulk-extract briefs or the underlying data, nor use the Service in a way that breaches the terms of the upstream data providers listed below. Source attributions shown in a brief must be preserved.

Where a data source imposes restrictions, those restrictions apply to your use of the brief. A brief does not grant you any licence to reuse underlying register data beyond your own due diligence.

The Provider makes no warranty beyond what is expressly stated in these terms. To the extent permitted by mandatory Swiss law, the Provider's liability is limited to the price you paid for the brief in question. The Provider is not liable for indirect or consequential loss arising from reliance on a brief — including decisions made in connection with a property transaction.

Nothing in these terms excludes or limits liability that cannot be excluded under mandatory Swiss law, including liability for intent (Vorsatz) or gross negligence (grobe Fahrlässigkeit).

These terms are governed by Swiss law. The place of jurisdiction is the Provider's Swiss domicile, subject to any mandatory consumer-protection venue available to you.

The Provider may update these terms; the version in force when you order governs that order. Questions about these terms can be sent to info@alpflo.ch.

These terms are written in English, which is the governing language. A German or French translation may be provided for convenience; in case of conflict the English version prevails. The version published at the time of your order governs that order.
