Privacy Policy

Last updated: April 1, 2026  ·  ~12 min read

We don't sell your data. We don't run ads.

Your learning data is used only to generate your personalized lessons. It is never used to train AI models.

What we collect Why Who processes it
Email and password Account creation and authentication Our authentication provider
Billing information Payment processing Stripe
Onboarding answers and learning goals Personalizing your learning paths Droplet Learn, our AI content provider
Learning interactions (views, saves, skips, completions) Generating relevant content and tracking progress Droplet Learn
Reflections and experiment notes Personalizing lessons and enabling your journaling Droplet Learn, our AI content provider
User preferences Customizing your experience Droplet Learn
Device and usage data Maintaining security and improving the service Our hosting and infrastructure providers

In plain language: We collect only what we need to run Droplet Learn. We don't sell your data. We don't run ads. Your learning data is sent to an AI provider (Anthropic) to generate your personalized lessons, but it is never used to train AI models.

1. Who we are

Droplet Learn is operated by Maple Spark Labs Inc., a limited liability company registered in Ontario, Canada, with its principal place of business in Toronto, Ontario, Canada. Full mailing address is available upon request for formal legal correspondence.

For privacy matters, you can reach our designated Privacy Officer at:

Throughout this policy, "Droplet Learn," "we," "us," and "our" refer to Maple Spark Labs Inc. "You" and "your" refer to you, the individual using our service.

2. Information we collect

We collect personal information in three ways: directly from you, automatically when you use the service, and from third-party service providers.

2a. Information you provide

When you create an account and use Droplet Learn, you voluntarily provide:

2b. Information collected automatically

When you use Droplet Learn, we automatically collect:

2c. Information from third parties

We do not purchase data about you from data brokers or other third-party sources.

3. How we use your information

We use your personal information for the following specific purposes:

To provide and personalize the service

To operate your account and process payments

To maintain and improve the service

To communicate with you

To comply with legal obligations

In plain language: We use your data to make Droplet Learn work for you — to create your personalized lessons, track your progress, and handle payments. We analyze anonymized patterns to improve the product. We never use your personal data for advertising or sell it to anyone.

4. How AI features process your data

This section explains exactly how your data interacts with artificial intelligence. We believe you deserve full transparency about this process.

What happens when AI generates your lessons

Droplet Learn uses the Anthropic Claude API to generate personalized educational content. Here is precisely what occurs:

  1. What we send to the AI: When generating your Drops, we transmit your learning goals, topic preferences, experience level, and relevant interaction history (such as which topics you've covered and your progress) to Anthropic's Claude API. We design our prompts to minimize personally identifiable information — we do not send your email address, name, or billing details to the AI.
  2. What the AI returns: Anthropic's system processes this context and generates educational content (lesson text, checklists, discussion prompts) which we then deliver to you as your personalized Drops.
  3. Where processing occurs: Anthropic's servers are located in the United States. Your learning context data crosses the Canadian border for AI processing.

Your data is not used to train AI models

Under our commercial API agreement with Anthropic, your data submitted through Droplet Learn is never used to train Anthropic's AI models. Anthropic's Commercial Terms of Service explicitly state: "Anthropic may not train models on Customer Content from Services." This is a firm contractual commitment, not a policy that can be quietly changed.

How long our AI provider retains your data

Our AI provider retains processing logs for a limited period as required for safety and abuse prevention, after which they are deleted. Their current retention practices are described in their published privacy documentation.

Reflections and experiment notes

When you write reflections or experiment notes, this text is stored in our database. If your reflections are used as context for generating future lessons, they follow the same AI processing pipeline described above. You can delete your reflections at any time.

In plain language: Your learning goals and progress get sent to our AI provider to create your lessons. They keep this data briefly for safety checks, then delete it. They never use it to train their AI. We never send your email, name, or payment info to the AI.

5. How we share your information

We do not sell your personal information. We do not share it with advertisers. We do not engage in data brokering. We share your information only with the following service providers, who process data on our behalf under contractual obligations to protect it:

Service provider Data shared Purpose
Cloud hosting and database provider Email, hashed password, session tokens, all application data Database hosting, authentication, data storage
Stripe Billing details, transaction records Payment processing
Anthropic Learning context, goals, preferences, interaction history AI content generation
PostHog Usage events, page views, feature interactions, IP address Product analytics and user behavior analysis
Sentry Error logs, stack traces, user context at time of error Error monitoring and debugging
Application hosting provider IP address, device info, usage logs Application hosting and delivery

Our service providers are primarily located in the United States. See Section 6 for details on international data transfers. A detailed list of specific service providers is available upon request.

Each provider is contractually required to:

Other circumstances where we may disclose your information

6. International data transfers

Droplet Learn is operated from Canada, but several of our service providers are based in the United States. This means your personal information is transferred to, stored in, and processed in the United States.

What this means for you: The United States has different privacy laws than Canada. Under US law, including the USA PATRIOT Act and the Foreign Intelligence Surveillance Act (FISA), US government authorities may access data held by US companies under certain circumstances. While we cannot prevent such access, we take the following steps to protect your data:

Under PIPEDA, we remain fully accountable for your personal information even when it is processed by a third party in another country.

In plain language: Your data is stored and processed on servers in the United States by our service providers. US privacy laws differ from Canadian ones. We protect your data through encryption and strict contracts with these providers.

7. Data retention

We retain your personal information only as long as necessary to fulfill the purposes described in this policy or as required by law.

Data type Retention period Reason
Account information Until you delete your account Required to provide the service
Learning paths, interaction history, reflections Until you delete your account (or delete individual items) Required to personalize your experience
Onboarding responses Until you delete your account Required for curriculum personalization
Billing records 7 years after the transaction Canadian tax law (Income Tax Act) requires retention of financial records
Server logs Limited period, typically no more than 90 days Security monitoring and debugging
AI processing logs Limited period per provider's safety requirements AI provider's trust and safety requirements
Support communications Reasonable period for quality assurance Quality assurance and dispute resolution
De-identified, aggregated analytics Indefinitely Product improvement (no longer personal information)

When you delete your account: We delete or anonymize your personal information within 30 days of your deletion request, except for data we are legally required to retain (such as billing records for tax purposes). Data held by third-party processors will be deleted according to our agreements with them and their published retention schedules.

8. Data security

We implement technical, organizational, and administrative safeguards to protect your personal information:

Technical measures

Organizational measures

Third-party security

No system is perfectly secure. While we take reasonable measures to protect your data, we cannot guarantee absolute security. If you become aware of a security vulnerability, please contact us immediately at info@maplesparklabs.com.

9. Your privacy rights

Depending on where you live, you have specific rights regarding your personal information. We honor these rights for all users, regardless of location.

Rights available to all users

To exercise any of these rights, contact us at info@maplesparklabs.com. We will verify your identity before processing your request and respond within 30 days, or notify you if additional time is needed.

Additional rights for residents of the European Economic Area (EEA) and United Kingdom

If you are located in the EEA or UK, you also have the right to:

Legal basis for processing (GDPR): Where GDPR applies, we process your personal information on the following bases:

International transfers: Data transferred from the EEA to the United States is protected by our data processing agreements with service providers. Canada has received an adequacy decision from the European Commission for PIPEDA-covered commercial activities, facilitating data transfers between the EU and Canada.

Additional rights for California residents

While Droplet Learn is a Canadian company and may not meet the CCPA/CPRA applicability thresholds, we extend the following rights to California residents as a matter of good practice:

We do not sell personal information. We do not share personal information for cross-context behavioral advertising. Because we do not sell or share personal information, a "Do Not Sell or Share" opt-out is not applicable.

In the past 12 months, we have collected the following categories of personal information as defined by the CCPA: Identifiers (email, IP address), Commercial information (subscription and transaction records), Internet or electronic network activity (usage data, interaction logs), and Inferences (learning preferences derived from your interactions).

10. Cookies and tracking technologies

Droplet Learn uses a minimal set of cookies and similar technologies:

Strictly necessary cookies

These are required for the platform to function. They include session cookies for authentication and security cookies. These cannot be disabled without breaking the service.

Analytics

We use PostHog for product analytics to understand how users interact with the platform. PostHog collects usage events, page views, and feature interactions. We use Sentry for error monitoring, which collects error logs and user context at the time of an error to help us diagnose and fix issues. Both tools process data in the United States under data processing agreements. If you are located in the EEA/UK, we will obtain your consent before activating non-essential analytics tracking.

What we do not use

For visitors from the EEA/UK: We will obtain your consent before placing any non-essential cookies, in compliance with the ePrivacy Directive. Essential cookies required for the service to function do not require consent.

In plain language: We use only the cookies needed to keep you logged in and the service running, plus PostHog for product analytics and Sentry for error monitoring. No advertising tracking. No social media widgets.

11. Children's privacy

Droplet Learn is not directed to individuals under the age of 18. We do not knowingly collect personal information from children under 18. If we learn that we have inadvertently collected personal information from a child under 18, we will take steps to delete that information as quickly as possible.

If you are a parent or guardian and believe your child has provided personal information to Droplet Learn, please contact us at info@maplesparklabs.com, and we will delete the account and associated data.

In accordance with the Office of the Privacy Commissioner of Canada's guidance, we treat children's personal information as particularly sensitive and requiring heightened protection.

12. Data breach notification

In the event of a data breach involving your personal information that creates a real risk of significant harm, we will:

We maintain records of all security incidents for a minimum of 24 months, as required by PIPEDA.

13. Changes to this policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or for other operational reasons.

How we will notify you

Your continued use of Droplet Learn after a change takes effect constitutes your acceptance of the revised policy. If you do not agree with a material change, you may delete your account before the change takes effect.

We will maintain a link to the previous version of this policy for your reference.
