Dueply

Terms of service

Last updated 3 October 2026

These terms govern the use of Dueply. By using the service you accept them. If you do not, do not use it.

What Dueply is, and is not

Dueply examines the flight you give it and tells you when you may be owed compensation or a refund for a delay or cancellation, under Regulation (EC) 261/2004 or, for flights to and from the United Kingdom, its UK version (UK261) or, for flights from Turkey and on Turkish carriers into it, the Turkish SHY-YOLCU regulation.

Dueply provides an automated estimate of whether you may be eligible, made by applying predefined rules to flight data supplied by a third party (AeroDataBox) and to your answers, and a draft letter you can edit. It is not a law firm and gives no legal or personalised advice: no lawyer reviews your case. It does not check circumstances it does not know, such as extraordinary circumstances claimed by the airline, reroutings or limitation periods.

Dueply does not act on your behalf: it files nothing, signs nothing in your name, and contacts no airline for you. Whether and how to act, the final content of the letter and sending it are yours: the letter goes from your address, in your name.

Dueply guarantees no recovery. Whether you get money back depends on the facts, the other party and the applicable rules, not on us.

Free service and packs

Each account can check up to three distinct flights for free per calendar month and have Dueply watch up to two flights at a time. Reopening a result or retrying after a technical failure does not use another check. Results, answers already given and the letter remain accessible without payment. Free checks also count per device: a new account opened on the same device in the same month adds none, and in the Android app they can be used only when Google Play verifies the app and the device.

In the Android app you can buy one-time packs that add checks and watched flights. What each pack contains and its total price, tax included, are shown in the app and again by Google Play before you confirm. There are no subscriptions, no automatic renewals and no share of any compensation you receive.

Bought credits are used after the free ones. A check credit is spent when you check a new flight; a watched-flight credit is spent when you start watching a flight beyond the free places, and is not returned when you stop watching it; if you start watching the same flight again, though, no further credit is spent. If a paid check or watch is not carried out because of us, we give the credit back.

Credits do not expire while your account exists. They are personal, not transferable and have no cash value. If you delete your account, unused credits are deleted with it. If we end the service, or close your account without you having breached these terms, we refund the paid credits you have not used, and tell you by email at least 30 days in advance, unless the end is forced by causes beyond our control.

Payment is handled by Google Play under its terms. Before a purchase we ask for your express consent to receive the credits immediately. You can withdraw from a pack without giving a reason within 14 days of buying it, as long as you have used none of its credits: we refund the full price. Once you use the first credit, you acknowledge that you lose the right of withdrawal (Art. 16(a) and (m) of Directive 2011/83/EU). To withdraw or ask for a refund, write to [email protected] or go to Google Play; if a pack is refunded, its unused credits are removed from your balance. After every purchase we send you a confirmation by email. If a purchase you paid for was not credited, write to us and we will fix it.

Your account

You must be at least 18 and provide a valid email address you control.

You are responsible for keeping your credentials safe; you are not liable for unauthorised use that is not due to a failing of yours. If you suspect unauthorised access, change your password and tell us.

You can delete your account at any time from Privacy and your data in the app settings. Deletion is permanent.

What you give us

The flight information you give us must be truthful: the correct flight number and date. A check run on wrong data produces a wrong result.

Acceptable use

Do not use Dueply for unlawful purposes, to pursue unfounded claims, or to attempt to reach anyone else's data.

Do not attempt to circumvent the service's technical limits, overload it, or extract its data by automated means.

If these terms are breached we may suspend or close the account, first giving you a reasoned notice and time to reply; we do so immediately only for fraud, technical abuse or a security risk. You can contest the decision by writing to [email protected]. If the account is closed for a serious breach, unused credits may not be refunded; in every other case we refund them.

Liability

We undertake to carry out the service with due care and to apply the rules described correctly to the data available. If a paid check or watch is not carried out, or is defective, because of us, you have the remedies Italian consumer law provides (Art. 135-octies ff. Codice del consumo): the credit restored, a correction or a refund.

We are not liable for errors caused by inaccurate flight data supplied by third parties or by inaccurate information you gave us, nor for circumstances the service, as described above, does not assess. The outcome of a claim depends on the airline and, if needed, a court or a competent body, not on Dueply.

Nothing in these terms excludes or limits our liability for wilful misconduct or gross negligence, for personal injury, or the rights the law gives you as a consumer that cannot be waived.

Ownership

The software, the name and the content of Dueply remain those of their authors. Your data remains yours: our use of it is what the privacy notice describes, and nothing more.

Changes to these terms

We may change these terms or the service only for valid reasons: changes in the law or case law, security needs, changes of data providers, new features or the correction of errors. Changes cost you nothing.

If a change is to your disadvantage we tell you by email at least 30 days in advance. You can withdraw within 30 days of the notice, or of the change taking effect if later, with a refund of the paid credits you have not used. If you do not withdraw, the change applies from the date given. We never reduce what a credit already bought entitles you to.

Guarantee and requirements

For the service you buy you have the legal guarantee of conformity under Art. 135-octies ff. of the Italian Consumer Code.

Dueply needs the Android app installed from Google Play. Free checks need Google Play Integrity to verify the app and the device; bought checks do not.

Governing law and forum

Italian law applies.

If you are a consumer, the courts of your place of residence or domicile remain competent, and the mandatory rights granted by the law of your country of residence are unaffected.
