Cookies are small text files that websites store on your device. They serve various purposes. Some are essential for the site to function, while others help us understand how visitors use our pages so we can make the experience better. This policy explains which cookies we use and why.
These cookies are necessary for the website to work. Without them, you would not be able to sign in, add items to your cart, or complete a purchase. We do not ask for consent for these because the site simply cannot function without them.

| ss_draft_session | Keeps the link to your book in progress so you can pick it up where you left off | 30 days |

| ss_iab_dismissed | Remembers that you dismissed the in-app browser notice so we do not show it again for a day | 24 hours |
| spark_currency | Stores the currency you selected so prices remain displayed in that currency on your next visit | 365 days |
These cookies help us understand how visitors interact with our website, which pages get the most traffic, where people drop off in the ordering flow, and what devices are most common. This data is aggregated and anonymous. We use it to fix problems and improve the experience, not to identify individual users.
We only load these cookies once you accept the "Analytics" category through the consent banner. Some are set directly by Spark Stories and others by our processors (Vercel Analytics, Klaviyo for on-site behaviour and newsletter segmentation, Google Analytics 4 loaded through Google Tag Manager). Our commercial newsletters are dispatched by Resend and Klaviyo is used solely for segmentation. These processors act on our behalf under the GDPR pursuant to a DPA and, where applicable, the European Commission's standard contractual clauses (SCC).

Our consent banner also offers a Performance category. It covers the technical monitoring tools that help us detect and fix issues, for example a page that fails to load. These tools may process technical data such as your browser type and the context of an error, and we only enable them if you allow this category.
With your consent, we use cookies set by our advertising partners (Google Ads, Meta for Facebook and Instagram, TikTok Ads, Pinterest Ads) to measure how our campaigns perform and to show you relevant offers on other websites and social networks. These cookies are orchestrated by our Google Tag Manager container and only fire once you have explicitly accepted the "Marketing" category in the consent banner.
Across the European Economic Area, the United Kingdom, Switzerland and Brazil, no advertising cookie is set until you have given prior consent, in line with the GDPR and the LGPD. In other jurisdictions where local law permits (United States, Canada, Australia, and similar), these cookies may be set on page load under an opt-out model, and you retain the ability to object at any time through the banner or from the bottom of this page.
