Who is responsible for your data

Sidefold is operated from Madrid, Spain. For the purposes of the EU General Data Protection Regulation (GDPR) and Spanish data-protection law, Sidefold is the data controller for personal data processed through the service.

Questions and privacy requests can be sent to hello@sidefold.co.

Data we collect

Creator accounts

When you sign in with Google, we receive your Google account identifier, verified email address, name, and profile picture. When you connect Instagram, we receive your Instagram account identifier, username, name, profile picture, granted permissions, and token-expiry information.

Creators can also sign up and sign in with an email address and password. We store your email address, account name, and a salted password hash, not your plaintext password. We send transactional email verification and password-reset messages through Cloudflare Email Service and store hashed, short-lived verification and reset tokens. Review accounts use the same access controls as other creator accounts and may have an access-expiry date.

Manuscripts and publications

When you choose a Google Doc, we process the selected file’s identifier, title, link, modification and revision information, text, structure, formatting, links, and images. We store a Sidefold copy of the imported manuscript so we can build and update your web reader, PDF, EPUB, creator page, and previews. We also store publication settings such as title, author, free chapters, lead-capture settings, custom domains, and affiliate details.

Lead magnets and reader delivery

When a reader requests a free resource, we store the publication and creator identifiers, reader email, access status, and delivery status so the creator can view the lead and Sidefold can provide the private access link. The reader can separately choose whether to receive marketing emails from the creator. If they opt in, we record the choice, time, language, and exact checkbox wording and show the choice to that creator. Free access does not depend on marketing consent. Readers can withdraw consent using the unsubscribe option in a marketing email or by contacting the creator. Sidefold does not collect payment-card or creator payout information for publications.

Optional email resources

If you request a blog resource through a Sidefold signup form, MailerLite processes your email address, the resource you request, and your subscription, confirmation, and unsubscribe status. Both resource forms use the same Sidefold mailing list. Your download link appears after signup; confirm your email to join the list. You can unsubscribe anytime.

Usage and support

With analytics consent, we process creator-page views, reader opens, lead requests, referral and campaign parameters, the event date, and a pseudonymous visitor identifier that is hashed before storage. Google Analytics may also receive browser, device, approximate-location, interaction, and network information. We process the messages and contact details you provide when you contact us. When you request a free creator resource, we store the email address you submit, show it to that resource’s creator as a lead, and use it to deliver your private access link.

How and why we use data

Provide the service
To create and secure accounts, import manuscripts, generate editions, host publications, deliver free resources, run automations, and provide creator dashboards. The legal basis is performance of our contract with you.
Optional creator emails
To record and show a reader’s separate marketing email choice to the creator whose free resource they requested. The legal basis for the optional marketing choice is consent.
First-publication help
To send a short series of practical setup emails when a creator has not published yet. When a signed-in creator follows one of these emails, we record the sequence step, click time, and whether a first publication is published within 30 days. This limited account-level attribution helps us evaluate the guidance without email-open tracking pixels. The series stops when you publish or use the unsubscribe link included in every message. Delivery, attribution, and preference records are kept so we can improve the service, respect your choice, and avoid duplicate messages. The legal basis is our legitimate interest in helping creators complete the service they joined and understanding whether that help works.
Connected services
To access the Google file or Instagram professional-account features you deliberately connect, including insights and creator-configured comment and direct-message automations. The legal basis is your consent and, where applicable, performance of the service you request. You can withdraw access through your Google or Meta account settings and by contacting us.
Security and reliability
To protect accounts, prevent abuse and fraud, troubleshoot errors, maintain records, and enforce our terms. The legal basis is our legitimate interests and compliance with legal obligations.
Sidefold subscriptions
To administer optional Sidefold Pro subscription billing and related accounting records. The legal basis is performance of a contract and compliance with legal obligations.
Optional analytics
To understand how Sidefold and creator storefronts are used and improve them. The legal basis is consent. Optional analytics remain off unless you accept them.

Sidefold does not sell personal data and does not use personal data for automated decisions that produce legal or similarly significant effects.

Google user data

Google sign-in requests openid, email, and profile. If you choose to connect Google Drive or a Google Doc, Sidefold separately requests drive.file. That permission lets Sidefold access only files you select for use with Sidefold or create through Sidefold; it does not give Sidefold general access to your Drive.

We use Google account data for sign-in, account identification, and optional first-publication guidance about the Sidefold account you created. Every guidance email includes an unsubscribe link. We use selected Google Drive data only to import, synchronize, format, publish, and export your manuscript at your direction. Access and refresh tokens are encrypted at rest and used only to provide these features.

Sidefold’s use and transfer of information received from Google APIs complies with the Google API Services User Data Policy, including the Limited Use requirements. Google user data is not used for advertising, sold, or used to train generalized artificial-intelligence or machine-learning models. It is shared only when necessary to provide or secure Sidefold, comply with law, or with your explicit direction.

Instagram data

Sidefold requests instagram_business_basic to identify a connected professional account and show its profile and selected media, instagram_business_manage_insights to retrieve account reach and profile-view metrics, instagram_business_manage_comments to receive and reply to comments on that account’s media, and instagram_business_manage_messages to receive and respond to messages sent to that account.

Creators can configure exact keywords and response text for automations. For a matching comment, Sidefold can publish the creator’s configured public reply and send the single private reply permitted for that comment. For a matching user-initiated direct message, Sidefold can send the creator’s configured response or publication link. Sidefold does not use these permissions to start unrelated conversations, publish Instagram posts, sell Instagram data, serve advertising, or train generalized artificial-intelligence or machine-learning models.

We store the connected account ID and username, encrypted access token, token expiry, and granted scopes. To run and measure an active automation, we also process the relevant Instagram-scoped sender or commenter ID and username, comment or message identifier and text, matched automation, and delivery status. This data is used only to match creator-configured keywords, prevent duplicate actions, deliver the requested response, troubleshoot failures, and show automation results. Insights are used to show the creator how Instagram reach compares with visits to their Sidefold publication. You can disconnect the account in Sidefold, remove Sidefold through Instagram’s connected-app settings, or request deletion using the instructions below.

Cookies, local storage, and analytics

Sidefold uses a secure, HTTP-only session cookie to keep signed-in creators authenticated. This cookie is necessary to provide the service and expires after 30 days. We also store your cookie choice in your browser so we can respect it.

Sidefold stores your analytics choice in a first-party cookie shared between sidefold.co and app.sidefold.co. If you accept analytics, Sidefold also stores a random visitor identifier in local storage for first-party publication analytics and loads Google Tag Manager, which may load Google Analytics measurement tags. These tools help us count visits, creator sign-ups, reader opens, lead requests, and link clicks and understand traffic sources. Analytics is not loaded before consent. You can reject analytics without losing access to Sidefold and can change your choice at any time through the “Cookie choices” control.

With analytics consent, we also use Microsoft Clarity on Sidefold’s website and creator app to understand clicks, scrolling, navigation, and where publishing attempts stop or fail. Clarity collects interaction, device, browser, and network data for heatmaps and session recordings and may use the _clck and _clsk cookies. Page text is masked, and we do not send manuscript text, names, email addresses, or publication titles as custom events. Clarity remains off until you accept analytics. Withdrawing consent clears its first-party cookies and reloads the page without Clarity. See the Microsoft Privacy Statement for more information.

Who processes data for us

We disclose data only as needed to operate Sidefold:

  • Cloudflare for hosting, content delivery, security, domains, lead-magnet delivery, and first-publication email.
  • MailerLite for optional resource signup forms, subscription preferences, and related emails requested by subscribers.
  • Google for sign-in, selected Drive files, Tag Manager, and consented analytics.
  • Microsoft Clarity for consented heatmaps, session recordings, and interaction analytics.
  • Meta for Instagram account connection, selected media, insights, comments, private replies, and user-initiated messaging features.
  • Stripe for optional Sidefold Pro subscription billing and fraud prevention.
  • Neon for managed PostgreSQL database storage.
  • Professional advisers or authorities where reasonably necessary to establish legal claims or comply with law.

Some providers may process data outside the European Economic Area. Where required, transfers rely on an applicable adequacy decision, standard contractual clauses, or another lawful safeguard.

Government and public-authority requests

Sidefold reviews each government or public-authority request for data before responding. We verify the requester’s identity and authority, the request’s legal basis, jurisdiction, scope, and required form. We reject or challenge requests that are invalid, unlawful, overly broad, or disproportionate, and ask the authority to narrow a request where appropriate.

If disclosure is legally required, we disclose only the minimum data responsive to the valid request, preserve confidentiality and security during transfer, and document the request, our assessment, the data disclosed, and the outcome. We notify affected users before disclosure unless prohibited by law or where notice would create a legally recognized risk. We preserve data only when legally required and for the required period. Sidefold has not received a government or public-authority request for Instagram Platform Data in the 12 months preceding 14 September 2026.

Retention and security

We keep account, publication, lead, and connected-service data while your account is active and for as long afterward as reasonably needed to complete a deletion request, resolve disputes, enforce agreements, or meet legal obligations. OAuth tokens are removed when the related connection or account is deleted, subject to limited backup retention. Sidefold subscription and accounting records are retained for the periods required by Spanish and EU law. Analytics is kept only as long as needed for reporting and is then deleted or aggregated.

We use HTTPS, secure session cookies, access controls, token hashing, and authenticated encryption for stored Google and Instagram credentials. No online service is completely secure, but we review safeguards in proportion to the data and risks involved.

Your privacy rights

Depending on your location, you may have rights to access, correct, erase, restrict, or receive a portable copy of your personal data; object to certain processing; and withdraw consent without affecting earlier lawful processing. These rights are free to exercise in most cases.

Email hello@sidefold.co from the address connected to your account. We may ask for reasonable proof of identity and will normally respond within one month. You may also complain to the Spanish Data Protection Agency (AEPD) or your local supervisory authority.

Disconnect or delete your data

Signing out ends the current session but does not delete your account. To delete a Google or Instagram connection, publication data, or your full Sidefold account, follow our data-deletion instructions or email hello@sidefold.co. We will verify the request, remove data that is no longer legally required, and confirm completion.

Changes to this policy

We may update this policy when Sidefold, our providers, or applicable law changes. Material changes will be announced through the service or by email where appropriate. The date at the top shows the latest version.
