Privacy Policy

Last updated: 5 October 2026

This Privacy Policy explains how Flík ehf. (“Flík”, “we”, “us” or “our”) collects, uses and protects your personal data when you use the Flík knitting calculator app for iPhone and iPad (and any web version) and our website at knitflik.com (together, the “Service”). We aim to collect as little personal data as possible and to be clear about what we do collect.

We process personal data in accordance with the EU General Data Protection Regulation (Regulation (EU) 2016/679, the “GDPR”) as it applies in the EEA, and the Icelandic Act on Data Protection and the Processing of Personal Data No. 90/2018.

We do not sell your personal data, and our website uses no advertising or tracking cookies. In the app, ad-measurement tracking happens only if you allow it through Apple App Tracking Transparency prompt.

1. Who we are

Flík ehf. is the controller responsible for the personal data described in this policy:

Company: Flík ehf.
Reg. no.: 550125-1290 (Iceland)
Email address: info@knitflik.com
Website: https://www.knitflik.com

If you have any questions about this policy or how we handle your data, or if you want to exercise your rights (see section 8), please contact us at info@knitflik.com.

2. What this policy covers

This policy applies to the Flík knitting calculator app for iPhone and iPad (and any web version) and to our website at knitflik.com. Some of the services we use — such as Apple, Paddle, RevenueCat, Mailchimp, AppsFlyer and Framer — process certain data under their own privacy policies. We link to those policies in section 5, and we encourage you to read them.

3. The data we collect, and why

We only collect what we need to run the Service, and we tell you the legal basis we rely on for each use:

Newsletter sign-up
If you subscribe to our newsletter, we collect your name and email address (through Mailchimp) so we can send you product updates and knitting tips. You can unsubscribe at any time using the link in any email.
Legal basis: your consent.

Calculator and project usage
We keep a count of your calculator and project usage — for example, how many calculations and projects you have used — anonymously, for the sole purpose of keeping track of your use of the app’s free tier across your devices. This data is not used for analytics, profiling or advertising. (Separately from these usage counts, a few in-app events are shared with AppsFlyer for ad-campaign measurement — see “Advertising measurement” below.) This usage data is not linked to you as a person. We can only identify you if you sign in to sync your data — in which case your usage is associated with your account so that your free usage and saved work carry over between devices.
Legal basis: our legitimate interest in operating the free tier fairly; where you sign in, performance of our contract with you.

Subscriptions and purchases
If you take out a paid subscription, your payment is handled by Apple (for App Store purchases) or Paddle (our merchant of record for purchases made through our website or in-app web checkout). We do not receive or store your full payment card details. We may receive limited information such as your email address, country and subscription status so that we can activate and manage your subscription, provide support, and keep the records we are required to keep.
Legal basis: performance of our contract with you, and compliance with legal obligations (such as accounting and tax requirements).

Advertising measurement (AppsFlyer)
We advertise the app on platforms such as Reddit and Instagram. To understand which campaigns actually bring people to the app, we use AppsFlyer, a mobile measurement provider. When you first open the app, the AppsFlyer SDK collects technical device information, your IP address, a random device identifier and an AppsFlyer-generated identifier, together with the campaign that led to the installation (or the fact that you found the app on your own). AppsFlyer also receives a small number of in-app events — completing sign-up, saving a calculation, and purchases (the latter forwarded by RevenueCat, our subscription-management provider) — so we can judge which campaigns bring in users who actually use the app.

When you first use the app, it shows Apple App Tracking Transparency prompt. Only if you tap Allow is your device’s advertising identifier (IDFA) used to link your install to a specific ad. If you decline, attribution instead relies on Apple’s privacy-preserving SKAdNetwork framework, which reports campaign results in aggregate form that does not identify you or your device.

We keep our own copy of the installation attribution (ad network and campaign name, and whether the installation was organic) on our servers, keyed by the same anonymous device identifier we use for free-usage tracking. Limited result signals (for example, “this campaign led to an installation or a purchase”) are sent back to the ad network to measure and improve our campaigns; these do not identify you.
Legal basis: your consent for identifier-based tracking (the App Tracking Transparency prompt); otherwise our legitimate interest in measuring the effectiveness of our advertising.

Account and saved content
Creating an account is optional — you can use the app without one. If you do create an account and sign in, we process your account details and all of your projects and calculations. They are backed up to the cloud automatically so that your work stays in sync and available across your devices. It is not possible to exclude individual projects or calculations from this backup — if you prefer to keep your work on your device only, simply use the app without signing in.
Legal basis: performance of our contract with you.

Messages you send us
If you email us at info@knitflik.com, we process your message and contact details so we can respond and help you.
Legal basis: our legitimate interest in responding to enquiries.

4. Cookies

Our website uses only the essential cookies required for it to work properly. We do not use third-party or advertising cookies, and we do not track you across other websites. The Mailchimp newsletter form embedded on our site does not set cookies or send any information to Mailchimp until you choose to submit it.

The website is hosted on Framer. Framer does not collect personal data from website visitors; see Framer’s cookie statement.

5. Who we share data with

We share personal data only with the service providers that help us operate the Service, and only as far as needed for them to provide their service to us. Each handles your data under its own privacy policy:

We do not sell your personal data, and we do not share it for third-party advertising. We may also disclose personal data where we are required to do so by law, or to protect our rights, users or the Service.

6. International data transfers

Some of the providers above are based outside the European Economic Area, including in the United States. Where your personal data is transferred outside the EEA, we rely on appropriate safeguards — such as the European Commission’s Standard Contractual Clauses or the EU–US Data Privacy Framework, where applicable.

7. How long we keep your data

We keep personal data only for as long as we need it:

  • Newsletter data — until you unsubscribe or ask us to delete it.

  • Calculator and project usage data — kept in anonymous form for as long as needed to apply free-usage limits; if you sign in to sync, it is kept with your account until the account is deleted.

  • Advertising attribution data — kept for up to two years, after which it is deleted or retained only in aggregated form.

  • Subscription and transaction records — for as long as needed to provide the Service and to meet our legal, accounting and tax obligations. Under Icelandic law, accounting records are generally kept for seven years.

  • Support emails — for as long as needed to handle your enquiry and for a reasonable period afterward.

8. Your rights

Under the GDPR and Icelandic data-protection law, you have the right to:

  • request access to the personal data we hold about you;

  • have inaccurate data corrected;

  • have your data erased;

  • restrict or object to our processing of your data;

  • receive your data in a portable format (data portability); and

  • withdraw your consent at any time, where we rely on consent — this does not affect processing carried out before you withdrew it.

To exercise any of these rights, email us at info@knitflik.com. We will respond within the time limits set by law.

You also have the right to lodge a complaint with the Icelandic Data Protection Authority, Persónuvernd (personuvernd.is), if you believe we have not handled your personal data properly.

9. Children

The Service is not directed to children under 13, and we do not knowingly collect personal data from them. Consistent with our Terms and Conditions, subscriptions are intended for users aged 18 or older. If you believe a child has provided us with personal data, please contact us and we will delete it.

10. Security

We take reasonable technical and organizational measures to protect personal data against loss, misuse and unauthorized access. While no method of transmission or storage is completely secure, we work to keep your information safe and to limit the data we hold in the first place.

11. Changes to this policy

We may update this Privacy Policy from time to time, for example to reflect changes to the Service or the law. When we do, we will revise the “Last updated” date at the top of this page and post the new version here. For significant changes, we will take reasonable steps to let you know.
