Terms of Service

PinDown.ai — Last updated: May 19, 2026

1. Scope, Provider, and Definitions

These Terms of Service ("Terms") govern the contractual relationship between Digital0, Willem Barents Strasse 29, 18106 Rostock, Germany ("Provider"), operating the PinDown.ai platform, and natural or legal persons ("User") who use the PinDown.ai cloud software-as-a-service offering.

The Service is offered to business customers and to consumers where applicable law grants consumer protection. If a provision applies only to one group, this is stated explicitly.

By registering, logging in, or actively using the Service, the User agrees to these Terms. The User's own terms and conditions do not apply unless the Provider expressly agrees to them in writing.

Privacy-related information is set out in our Privacy Policy at /privacy-policy. Business customers may enter into a separate Data Processing Agreement (DPA) where required.

2. Service Description and Brand Distinction

PinDown.ai is an AI-powered platform for structuring, linking, and visualizing information. Users may use pins, pages, pinboards, walls, timelines, projects, showcases, kanban boards, and AI chat, subject to the selected plan.

Technical delivery may include agent-based processing, documented API access, and connections to third-party AI providers. Features depend on the User's subscription tier.

Distinction from Pinterest

PinDown.ai has no business, legal, trademark, or organizational affiliation with Pinterest Inc. PinDown.ai is not a social network for public image sharing or visual bookmarking; it is a software tool for professional and personal knowledge management.

3. Registration, Account, and Authentication

(1) User account

Core features require a user account. The User must provide accurate information and keep it up to date.

(2) OAuth / federated login

Login is provided through third-party identity services (currently including Google and GitHub). Additional providers (e.g. Apple, Microsoft) may be added. There is no entitlement to a specific login method.

The User must protect credentials with the respective identity provider. The Provider is not liable for unauthorized access resulting from compromise of the User's third-party account.

(3) Minimum age

Use requires a minimum age of 16 in the European Economic Area, or 13 elsewhere where permitted by law. Minors need consent from a parent or guardian.

(4) Suspension

The Provider may suspend or terminate access temporarily or permanently in case of suspected abuse, breach of these Terms, or payment default.

4. Right of Withdrawal (Consumers)

Applies to consumers only, where mandatory law provides a right of withdrawal.

Withdrawal notice

You have the right to withdraw from this contract within fourteen (14) days without giving reasons. The period starts on the day the contract is concluded.

To exercise your right, send a clear statement to support@pindown.ai (subject: Withdrawal).

If you withdraw, we will refund all payments received from you without undue delay and at the latest within fourteen (14) days of receiving your notice, using the same payment method unless otherwise agreed. Payments may be processed by Paddle as Merchant of Record.

Early expiry of the right of withdrawal

For digital content/SaaS, your right of withdrawal expires early if we began performance after you (1) expressly agreed that we start before the withdrawal period ends, and (2) confirmed that you lose your right of withdrawal once performance begins.

5. Payments via Paddle (Merchant of Record)

(1) Payment contracting party

Paid subscriptions and credit packages are sold through Paddle.com (Paddle.com Market Limited and affiliates) as Merchant of Record. The User enters into a direct contractual relationship with Paddle for payment, invoicing, and tax.

The software license between User and Provider is governed by these Terms in parallel.

(2) Payment and invoices

Payment methods, prices, and taxes are shown at Paddle checkout. Charges occur at purchase and at the start of each billing period. Invoices are provided electronically by Paddle.

(3) Cancellation

Cancellations and plan changes are made via the Paddle customer portal or paths described in the app. After cancellation, access continues until the end of the paid period unless stated otherwise.

Discretionary refunds: available for monthly subscriptions only within 14 days of first subscribe (see /refund-policy). Annual subscriptions are paid in advance and are not eligible for discretionary refunds; you may still cancel renewal so access continues until the end of the paid year. Mandatory consumer withdrawal rights (Section 4) remain unaffected where applicable.

6. Plans, Usage Limits, and Credits

(1) Plans

The Provider offers plans including (names and prices at checkout or in the dashboard):

  • Playground (free): limited use, including pin limits (currently max. 5 pins per day and 50 pins total), format creation limits, and upload size (currently 5 MB per file on Playground).
  • Core (paid): monthly credit allowance (currently 500 credits per billing month) and higher limits.
  • Workspace (paid): higher monthly credit allowance (currently 1,500 credits per billing month) and plan-dependent collaboration features (e.g. organisations, roles).

(2) What credits are used for

Credits are the internal unit for metered, AI-powered and related platform usage. They are consumed when you use features that incur variable infrastructure cost, including but not limited to:

  • AI chat and agent-assisted actions in the product.
  • AI-assisted creation, editing, structuring, or transformation of pins, pages, formats, and project content.
  • Workflow and automation runs that call large language models or similar services.
  • Image generation and other premium AI tools where offered on your plan.
  • Document or media processing that uses third-party AI APIs on your behalf.

The number of credits per action depends on the model used, input/output size, and complexity. Current estimates and usage history are shown in your dashboard. The Provider may change credit rates for new usage with reasonable notice; binding figures for your account are those displayed at the time of use.

(3) Two credit balances: monthly allowance and purchased (top-up) credits

Your account maintains two separate credit pools. Your total spendable balance is the sum of both.

  • Monthly allowance credits (subscription credits): included with Core or Workspace for each billing month (or each monthly tranche on annual billing). They are refilled at the start of a new paid billing period to your plan cap (500 Core / 1,500 Workspace, unless changed in product). Unused monthly allowance does not roll over to the next period — each period starts with a fresh monthly bucket up to your plan cap.
  • Purchased credits (top-up / add-on credits): bought separately via credit packs in the app (processed by Paddle). They are added to your purchased balance, do not expire while your account remains active, and are not reset when your subscription renews or when your plan changes.

(4) Order of consumption

When you use metered features, the system deducts credits in this order: (1) monthly allowance credits first, until that pool is exhausted for the current period; (2) then purchased (top-up) credits. Partially failed or aborted AI operations may still consume credits where infrastructure was used, as shown in your usage history.

(5) Subscription renewal and end of billing period

On each successful renewal of a paid subscription (monthly or annual billing cycle as shown by Paddle), a new billing period begins. Your monthly allowance is reset to the full amount for your current plan. Credits you already consumed in the previous period do not reduce the new period's allowance. Purchased (top-up) credits are unaffected and remain in your account.

If your subscription ends (cancellation, non-renewal, or refund), paid plan features and monthly allowance access end as described below. Purchased credits may remain on the account but can only be used while you have an active paid subscription that permits metered AI usage, unless we state otherwise in the product.

(6) Upgrades (e.g. Core → Workspace)

If you upgrade an existing Paddle subscription in the app, the higher plan and its features generally take effect immediately after successful payment processing (including prorated charges for the remainder of the current billing period, as calculated by Paddle).

Your monthly allowance is reconciled to the new plan cap for the current billing period — you do not receive a full new cap on top of credits already spent. Example: if you used 100 monthly allowance credits on Core in the current period and upgrade to Workspace (1,500 cap), your remaining monthly allowance for that period becomes 1,400 (1,500 minus 100). Purchased (top-up) credits are not reduced by an upgrade.

(7) Downgrades (e.g. Workspace → Core)

If you downgrade, the change is scheduled for the end of your current paid billing period, not immediately. Until that date you keep your current plan's features and monthly allowance rules for that period — you already paid for the higher tier for this cycle.

When the scheduled downgrade takes effect at period end, your plan, price, and monthly allowance cap change on renewal (e.g. to 500 credits per month on Core). You may cancel a scheduled downgrade before it takes effect via the in-app billing controls, if available.

(8) Cancellation, payment failure, and return to Playground

If you cancel a paid subscription, you typically retain Core or Workspace access and can spend remaining credits until the end of the billing period you already paid for. After that date you are moved to Playground (free tier limits). You may be able to resume before period end if offered in the app.

If payment fails or your subscription is past due, paid features and use of monthly allowance may be suspended until payment is resolved; entitlements may effectively match Playground until Paddle confirms successful payment.

(9) Annual billing

If you subscribe on an annual billing interval, you are still charged annually through Paddle, but your monthly credit allowance may be credited in monthly tranches within that year (not as one lump sum of twelve months of credits on day one), as configured in the product.

(10) General credit rules

  • Credits are non-transferable between accounts.
  • Credits have no cash value and are not redeemable for money, except where mandatory law or our Refund Policy requires otherwise.
  • Credit pack (top-up) purchases are separate transactions and are not refundable except where required by law (see /refund-policy).
  • Annual subscription fees are non-refundable under our discretionary refund policy; cancel to stop renewal at period end.
  • We may freeze or adjust balances in case of abuse, chargebacks, or billing disputes.

(11) Platform capacity

The Provider may throttle or restrict features when operational limits are reached (e.g. open-beta chat capacity). Mandatory statutory rights remain unaffected.

7. Infrastructure and Data Storage

The Service runs on Google Cloud Platform and Google Firebase (Realtime Database, Storage, Authentication). The target configuration is operation in EU data centers (including region europe-west1). Data is encrypted in transit and at rest using industry-standard methods.

The Provider does not guarantee uninterrupted availability; maintenance and third-party cloud outages may cause interruptions.

8. Artificial Intelligence and Third-Party Models

AI features use selected third parties, including Google (Gemini), OpenAI, and Perplexity, and may use additional services (e.g. Document AI, web search). Not every request is processed in a single data center; we prefer configurations with strong data protection where offered by vendors.

We do not use your content to train public models. Processing occurs to deliver features you trigger.

AI outputs may be incomplete or wrong ("hallucinations"). You must review outputs before business or legal use.

9. API Access

Where API keys are provided, they must be kept confidential and must not be posted in public repositories. You are responsible for usage and credit consumption via your keys.

Rate limits and abuse protection may revoke API access. The Provider may change or discontinue endpoints with reasonable notice.

10. Beta and Preview Features

Experimental features and preview models ("Beta") may change or be removed at any time. They are provided "as is"; warranty and liability are excluded except for intent and gross negligence where law does not permit exclusion.

11. Sharing, Organizations, and Collaboration

Users may invite others to organizations (e.g. editor/viewer roles) and share via share links. You are responsible for ensuring shared content does not infringe third-party rights or expose confidential data without authorization.

The Provider may disable share links and collaboration access in case of abuse.

Public community marketplaces, if offered, are additional features subject to the prohibitions in Section 12.

12. User Content, Uploads, and Acceptable Use

(1) Your content

You retain rights in your content. You grant the Provider a non-exclusive, worldwide, royalty-free license to store, process, display, and use content to perform the contract (including AI processing and backups).

(2) Your obligations

You represent and warrant that:

  • You have rights to uploaded files (PDF, Office, images) and embedded URLs (websites, YouTube).
  • You will not upload or share unlawful, discriminatory, violent, or pornographic content.
  • You will not infringe copyright, trademark, or personality rights.
  • You will not scrape the platform outside documented APIs.
  • You will not reverse engineer the Service or train competing models on platform outputs.
  • You will not circumvent limits, conduct DDoS attacks, or introduce malware.

(3) Moderation

The Provider may remove content and suspend accounts for violations. We are not obliged to pre-screen all content.

13. Warranty, Availability, and AI Disclaimer

Consumers retain mandatory statutory rights for digital services. For business customers, warranty is limited to twelve (12) months from provision where permitted by law.

Target annual dashboard availability: approximately 99.0%, excluding maintenance and force majeure.

No liability is accepted for accuracy, legal effect, or commercial usability of AI outputs.

14. Limitation of Liability and Indemnity

(1) Unlimited liability

Unlimited liability applies for intent, gross negligence, injury to life, body, or health, and under product liability law.

(2) Limited liability

For slight negligence of essential contractual duties, liability is limited to foreseeable, typical contract damages. For business customers, indirect damages, lost profit, and data loss are excluded where permitted.

(3) Indemnity

You indemnify the Provider against third-party claims arising from unlawful use, breach of these Terms, or unverified reliance on AI outputs shared with others.

15. Term, Termination, and Data After Contract End

Paid contracts run for the selected term and renew automatically unless cancelled via Paddle. Consumers may have additional cancellation rights under mandatory law.

You may delete your account in settings or contact support@pindown.ai. After deletion, personal data and content are deleted or anonymized within 90 days unless legal retention applies (see Privacy Policy).

16. Changes to These Terms

We may update these Terms. Material changes will be announced by email and/or in the dashboard at least 30 days before they take effect. If you continue using the Service without objecting, the new Terms apply. Consumers may have a special right to terminate where mandatory law requires.

17. General Provisions

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, this applies only insofar as mandatory protections of the country of residence are not deprived.

If the User is a merchant, legal entity under public law, or public-law special fund, exclusive jurisdiction is Rostock, Germany.

If any provision is invalid, the remainder stays in effect. The Provider may assign rights and obligations in connection with a business transfer; the User may not assign without consent.

The authoritative language of these Terms is English.
