8. Account Deletion and Data Export
8.1 Account Deletion (GDPR Art. 17)
You can delete your account at any time directly within the app or via our website at https://lets-glow.de/account-loeschen. This way, you always have the option to fully delete your account, even without the app. The deletion process works as follows:
- Grace Period: After your deletion request, you have 30 days to reverse the deletion.
- Complete Deletion: After the grace period, all your data will be irreversibly deleted:
Account data (Firebase Auth)
Profile data (Firestore)
Posts, comments, challenges
Uploaded media (Storage)
Team memberships and references
The technical completion of full deletion may take up to 90 days after the grace period (e.g., for removal from backups and cache systems). During this time, your data is no longer accessible.
3. Automated Cleanup: A scheduled cleanup process (scheduledPrivacyCleanup) ensures that expired deletion requests are fully executed.
Exceptions to Deletion:
- Audit logs are anonymized, not deleted (legal documentation obligation, 10 years).
- Aggregated, anonymized statistics are retained.
8.2 Data Export (GDPR Art. 15 / Art. 20)
You can request an export of your stored data at any time within the app. The export includes:
- Account and profile data
- Posts and comments
- Challenges and scores
- Team memberships
The export is provided as a JSON file and is available for download for 7 days.
9. Content Moderation and Community Safety
9.1 Reporting
Users can report other users, posts, or challenges. The following data is processed:
- Reason for the report and details
- Type of reported content (user, post, challenge)

10. Email Communication
We use emails for the following purposes:
- Transactional Emails: Account verification, PIN codes for critical actions, security notifications

Emails are sent via a German host (ALL-INKL SMTP). We do not send marketing emails without your explicit consent.
11. AI Features (Artificial Intelligence)
11.1 Use of AI
Challenges on Let's Glow are created by the community or set up as personal/team challenges – not by AI. We use AI-powered features in a supporting role:
- Content Review: All challenges – whether community, personal, or team challenges – are automatically reviewed for community guideline compliance (first check before human review)
- Categorization: Automatic classification and tagging of challenges
- Text Generation: AI-assisted creation of descriptive texts and summaries
AI services from OpenAI, Anthropic, and Google are used for this purpose (see §6.3). No personal user data is transmitted to these services.
11.2 Automated Decision-Making (Art. 22 GDPR)
The AI-based content review may result in challenges being automatically held back for human review. No purely automated decisions are made that significantly affect you legally — every rejecting decision regarding your content is reviewed by our moderation team. You have the right at any time to request human review, to express your point of view, and to contest the decision (see Community Guidelines, Section 6: Right of Appeal).
12. Cookies and Tracking
12.1 Flutter App (iOS / Android)
The mobile app uses no cookies. Tracking is performed exclusively via Firebase Analytics (with your consent). If we use Google Tag Manager in the future (e.g. for web), we will do so without personal data and only with your consent.
12.2 Web Applications (Admin Panel)
The web applications use Firebase Authentication session cookies, which are strictly necessary for authentication and session management (technically required cookies). No marketing or tracking cookies are used.
13. Security Measures
We protect your data through technical and organizational measures, including encryption during transmission and storage, role-based access control, and regular security reviews. No personal data is processed during AI-based content review.
14. Your Rights (Art. 15–21 GDPR)

Our Mission
Small actions. Big impact.
Let's Glow is a space for small steps with big impact — a place where people meet each other first as humans and the good we can do for one another becomes visible. Challenges from the community and from friends motivate you to step outside your comfort zone — or to strengthen it. With small tasks for growth, togetherness, and sustainability, your everyday life becomes a game: playful, motivating, and without comparison.
Sustainability should feel good — without sacrifice, without perfection. Every step counts.
No pressure, no obligations. You always decide for yourself whether and how you participate.
Let's Glow together.

We are continuously working on additional AI features to provide you with a better experience. New AI features will be transparently explained to you before use.
9. Paid Services and Subscriptions
9.1 Payment Processing (IAP and Stripe)
Purchases of digital content within the app (subscriptions, Stars, premium features) may – depending on product and platform – be processed through the Apple App Store or Google Play Store (in-app purchase, IAP) or through our payment provider Stripe. For purchases on our website (outside the app), we use Stripe. The terms and conditions of the respective payment channel (store or Stripe) apply.
You can restore previous purchases at any time on another device (Restore Purchase), as long as you are signed in with the same store account (for IAP purchases).
9.2 Prices and Transparency
All prices are displayed as total prices before purchase. Pursuant to § 19 UStG (German Small Business Regulation), no VAT is charged. There are no hidden costs.
9.3 Subscriptions
- Subscriptions automatically renew for the selected period unless you cancel before the end of the current term.
- Cancellation is done through your app store settings:
- Apple: Settings → [Your Name] → Subscriptions → Let's Glow → Cancel Subscription
- Google Play: Manage Subscriptions → Let's Glow → Cancel
- Stripe (Website): Via your account on lets-glow.de or by email to support@lets-glow.de
- Pursuant to § 312k BGB (German Civil Code), you can easily cancel your subscription via the app or our website (lets-glow.de).
- Already paid periods will not be refunded on a pro-rata basis.
9.4 In-App Currency ("Stars")
- Stars can be purchased within the app and used for certain features (e.g. as virtual pledge or commitment for challenges). They are usage rights within the app only.
- Stars have no monetary equivalent and cannot be cashed out, transferred to third parties, or refunded, unless required by applicable law.
- Unused Stars expire upon account deletion.
9.5 Provider Offers and Our Role as Intermediary
Offers from partners (e.g. local businesses, restaurants) in the app ("provider goodies", invitations, match codes) are not provided by us as voucher sales. You can use Stars earned in the app to reveal a promo or match code and present it to the partner on site. Payment for the actual service (e.g. meal, admission) is made directly between you and the provider on site. Let's Glow acts only as an intermediary or advertising platform and is not a party to that contract. The respective provider is solely responsible for code redemption, quality of the service, and availability.
9.6 Spark – Voluntary Monthly Support
Let's Glow is a passion project. With "Spark", you can voluntarily support us on a monthly basis – not a mandatory subscription, but a contribution to the ongoing development of the app.
- Equal treatment: All Sparks receive the same benefits, regardless of the chosen contribution amount. There are no tiered VIP levels or premium hierarchies.
- Contributions: You choose a fixed monthly amount from the available tiers (e.g. EUR 4.99 to EUR 19.99). The chosen amount can be changed at any time; changes take effect from the next billing period.
- Benefits: Sparks receive cosmetic community features (e.g. a Spark badge on the avatar, access to the Spark forum, participation in polls). Spark provides no gameplay advantages – no extra XP, Stars, premium challenges, or priority support.
- Spark Streak and Milestones: Consecutive months as a Spark are counted. At certain milestones (e.g. 3, 6, 12 months) you receive purely cosmetic rewards (e.g. exclusive avatar frames, backgrounds). These rewards have no monetary value.
- Payment processing: Spark is processed via Stripe (see Section 9.1). Stripe's terms of service apply. Pursuant to § 19 UStG (German Small Business Regulation), no VAT is charged.
- Cancellation: Possible at any time at the end of the current billing period – directly in the app (§ 312k BGB: two-click cancellation) or by email to support@lets-glow.de. After cancellation, your Spark benefits remain active until the end of the paid period.
- Right of withdrawal: The statutory 14-day right of withdrawal applies (§ 312 BGB, see Section 10).
- Not electronic money: Spark is a service subscription; no credit balance is created and there is no entitlement to a payout.
- Right to modify: We reserve the right to adjust the available contribution tiers, benefits, and milestones. Material changes will be communicated in accordance with Section 15 of these Terms of Service.
9.7 Free Usage with Advertising
As an alternative to paid usage, you can use Let's Glow for free with advertising. Further information on data processing in connection with advertising can be found in our Privacy Policy.
10. Right of Withdrawal
10.1 Statutory Right of Withdrawal
As a consumer, you have the right to withdraw from any contract for paid services within 14 days without giving any reason. The withdrawal period begins on the day the contract is concluded.
10.2 Exercising Withdrawal
Send a clear declaration to:
Johannes Reusch
Heinrich-Heine-Platz 9A
10179 Berlin, Germany
Email: support@lets-glow.de
10.3 Early Expiration
The right of withdrawal expires prematurely if we have begun performance of the contract after you:
- Expressly agreed that we may begin performance before the expiration of the withdrawal period, and
- Confirmed that you thereby lose your right of withdrawal.
When purchasing through an app store, the withdrawal rules of the respective store additionally apply.
10.4 Detailed Withdrawal Instructions
The complete withdrawal instructions, including a model withdrawal form, can be found in our separate "Withdrawal Policy" document.
11. Account Deletion
11.1 Your Right to Deletion
You can delete your account at any time and without giving any reason – directly in the app under Settings or via our website at https://lets-glow.de/account-loeschen. This way, you always have the option to fully delete your account, even without the app. Your right to deletion under GDPR Art. 17 remains unaffected.
11.2 What Happens Upon Deletion?
- 30-Day Grace Period: After your deletion request, you have 30 days to reverse the deletion. During this time, your account is deactivated but not deleted.
- After 30 Days: All your personal data is irreversibly deleted, including profile data, posts, challenges, and team memberships.
- Exceptions: Statutory retention obligations (e.g., audit logs for 10 years) remain unaffected.
11.3 Data Export
Before deletion, you have the option to export your data via the app (GDPR Art. 15 and Art. 20). The export includes all personal data we have stored about you.
12. Intellectual Property
12.1 Rights of Let's Glow
The app, including its design, code, the "Let's Glow" brand, graphics, texts, and all other content (insofar as not user-generated), is protected by copyright and owned by us. Any unauthorized use is prohibited.
12.2 Your Rights
Your user-generated content belongs to you (see Section 6). Use of the app does not grant you ownership of any part of the app software or the Let's Glow brand.
13. Liability
13.1 Liability of Let's Glow
We are liable without limitation for damages we have caused intentionally or through gross negligence. For injury to life, body, or health, we are also liable in cases of ordinary negligence — provided the breach of duty is attributable to us. In cases of slightly negligent breach of material contractual obligations (cardinal obligations), our liability is limited to foreseeable, contract-typical damages. Otherwise, liability is excluded to the extent permitted by law. Liability under product liability law and for fraudulently concealed defects remains unaffected. Any contributory negligence on the part of the user (§ 254 BGB) shall be taken into account — in particular if the user disregards safety guidelines or undertakes obviously unsuitable actions.
13.2 User-Generated Content
We assume no liability for content created or shared by users. Responsibility lies with the respective creators.
13.3 Third-Party Services
Let's Glow uses third-party services (e.g., Firebase, OpenAI, Stripe, Apple, Google). For disruptions, outages, or data loss caused exclusively by these third parties, we are only liable within the limits set out in § 13.1.
13.4 Nature of the Service
Let's Glow is a platform for short, everyday impulses and suggestions — such as "Buy someone flowers", "Write a letter to an old friend", or "Try a new recipe." Let's Glow does not provide personal advice, coaching, therapy, medical recommendations, or AI-driven life counseling. There is no ongoing advisory or supervisory relationship between Let's Glow and its users.
13.5 Challenges, Impulses and Personal Responsibility
Challenges are predominantly created by users and the community. We review content through automated and manual moderation for obvious violations, but cannot guarantee that every piece of content is safe in every individual context.
Your own judgment is the decisive safety mechanism. You alone decide whether and how you take on a challenge. This decision lies exclusively with you. In particular:
- Challenges are suggestions — not instructions, not directives, not orders. There is no obligation whatsoever to carry out a challenge.
- If you consider a challenge to be dangerous, a health concern, illegal, or unsuitable for you, do not carry it out.
- You bear full responsibility for whether you follow a suggestion and how you carry it out — regardless of whether the content was created by Let's Glow, the community, or an AI.
- Please review the Safety Checklist and the Personal Responsibility Notice.
There is no advisory or supervisory relationship between a short everyday impulse and the manner in which a user carries it out. Liability of Let's Glow is excluded for damages arising from a user following content that they should have recognized as obviously dangerous, illegal, or harmful to health by exercising ordinary care, to the extent that no fault on our part is involved. Our statutory liability under § 13.1 remains unaffected.
14. Termination
14.1 Termination by You
You may terminate the usage contract at any time and without giving any reason by deleting your account (see Section 11).
14.2 Termination by Us
We may terminate the usage contract for good cause, particularly if:
- You repeatedly violate these Terms of Service or the Community Guidelines
- You provided false information during registration
- You misuse the app for illegal purposes
Before termination, we will inform you of the reason. You have the right to appeal (see Section 7.6).
15. Changes to the Terms of Service
15.1 Right to Amend
We reserve the right to amend, supplement, or modify these Terms of Service at any time – in particular where required or appropriate due to changes in law, new or modified features (e.g. introduction or modification of subscription models such as Spark, payment methods, benefits, or pricing tiers), technical developments, changed business processes, or to improve the user experience.
15.2 Notification
We will inform you of material changes at least 30 days before they take effect – via in-app notification or through our consent system, which requests your explicit agreement. This gives you plenty of time to review the changes. Minor editorial corrections or clarifications that do not materially affect your rights and obligations may be made without separate notification.
15.3 Objection
If you do not agree to the changes, you may delete your account at any time. Continued use of the app after the changes take effect constitutes acceptance of the amended terms.
16. Governing Law and Jurisdiction
16.1 Governing Law
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG).
16.2 Jurisdiction
The place of jurisdiction is Berlin, to the extent permitted by law.
16.3 Online Dispute Resolution
The European Commission provides an online dispute resolution (ODR) platform: https://ec.europa.eu/consumers/odr. Our email address: support@lets-glow.de. We are neither obligated nor willing to participate in dispute resolution proceedings before a consumer arbitration board.
17. Severability Clause
Should any provision of these Terms of Service be or become invalid, the validity of the remaining provisions shall not be affected. The invalid provision shall be replaced by a valid provision that most closely reflects the economic purpose of the invalid provision.
18. Special Provisions for App Store Distribution
If you downloaded Let's Glow from the Apple App Store or Google Play Store, the following additional provisions apply. In case of conflict with other sections, these provisions shall prevail.
18.1 Contractual Partner and Responsibility
Your agreement regarding the use of Let's Glow is exclusively with Johannes Reusch (Provider, see Section 1.2), not with Apple Inc. or Google LLC. We are solely responsible for the app, its content, maintenance, support, and all claims arising from its use.
18.2 Apple as Third-Party Beneficiary
Apple Inc. and its subsidiaries are third-party beneficiaries of these Terms of Service. By agreeing to these terms, Apple obtains the right to enforce them as a third-party beneficiary. This right of Apple exists regardless of any other agreements between Apple and us.
18.3 Store Operator Liability
Neither Apple Inc. nor Google LLC are obligated to provide any maintenance or support services for Let's Glow. To the maximum extent permitted by applicable law, Apple and Google disclaim any warranty obligations for the app – except where the applicable warranty obligation lies with us.
18.4 Product Claims and Warranty
In the event that the app does not conform to any applicable warranty, you may – if you obtained the app through the Apple App Store – notify Apple through the purchase price refund process. Apple has no further warranty obligations beyond this. All other claims, losses, liabilities, damages, costs, or expenses arising from any failure to meet warranties are our sole responsibility.
18.5 Intellectual Property Claims
Should any third party claim that the app or your use of the app infringes third-party intellectual property rights, we – not Apple or Google – are solely responsible for the investigation, defense, settlement, and discharge of any such claims.
18.6 Export Compliance and Sanctions
You represent that you are not located in a country subject to a U.S., EU, or German government embargo, and that you are not listed on any sanctioned persons list. You agree to comply with all applicable export control laws and sanctions regulations when using the app.

Liability for Content
As a service provider, we are responsible for our own content on these pages in accordance with general laws pursuant to § 7(1) DDG. However, pursuant to §§ 8 to 10 DDG, we are not obligated to monitor transmitted or stored third-party information or to investigate circumstances that indicate illegal activity.
Obligations to remove or block the use of information under general laws remain unaffected. However, liability in this regard is only possible from the time of knowledge of a specific legal violation. Upon becoming aware of corresponding legal violations, we will remove such content immediately.
Liability for Links
Our offering contains links to external third-party websites over whose content we have no influence. Therefore, we cannot assume any liability for such external content. The respective provider or operator of the linked pages is always responsible for the content of the linked pages.
The linked pages were checked for possible legal violations at the time of linking. Illegal content was not apparent at the time of linking. However, permanent content monitoring of the linked pages is unreasonable without concrete evidence of a legal violation. Upon becoming aware of legal violations, we will remove such links immediately.
Copyright
The content and works created by the site operators on these pages are subject to German copyright law. Reproduction, editing, distribution, and any form of utilization beyond the limits of copyright law require the written consent of the respective author or creator.
Downloads and copies of this site are only permitted for private, non-commercial use. Insofar as the content on this site was not created by us, the copyrights of third parties are respected. In particular, third-party content is identified as such. Should you nevertheless become aware of a copyright infringement, please inform us accordingly. Upon becoming aware of legal violations, we will remove such content immediately.
